Design insights into eutectic solvents: Selective recovery of transition metal elements from laterite nickel ore leachate SCIE
期刊论文 | 2025 , 361 | SEPARATION AND PURIFICATION TECHNOLOGY

Abstract :

In response to growing environmental concerns, hydrophobic eutectic solvents (HES) have emerged as promising green alternatives for sustainable metal extraction. However, a comprehensive understanding of how variations in HES composition affect extraction sequence remains elusive, impeding the development of theoretically guided solvent designs. In this study, the precursors of HES, including tri-n-octylamine (TOA), benzoyltrifluoroacetone (HBTA), 2-thenoyltrifluoroacetone (HTTA), and n-decanol (DL), were efficiently screened using conceptual density functional theory (CDFT). The Activation Strain Model (AMS) was applied to decompose the interaction energy into electrostatic and orbital contributions, clarifying the dual-controlled reactivity between metal ions and HES. Reactivity studies indicate that DL improves extraction selectivity via kinetic control and solvation energy, while TOA enhances extraction rates through thermodynamic control. Based on these insights, two HES with low viscosity (<17.6 mPa & sdot;s), low water solubility (TOC <400 mg/L), and low moisture content (<2%) were selected for sustainable recovery of transition metals from laterite nickel ore leachate. HES has excellent separation performance, with an extraction rate of 98 % for Cu (II) using HTTA: DL (2:9) and almost no extraction for Co (II) or Ni (II). The separation factors beta (Ni/Mn) and beta (Co/Mn) of TOA: HTTA: DL (1:2:9) reach 1543 and 549, respectively. The HES retained stability over five extraction-stripping cycles. Based on the extraction performance of two HES, an environmentally friendly, streamlined NCM precursor production process has been developed. This study provides a new paradigm for the rational design and mechanism research of HES in metal extraction applications.

Abstract :

A simple hydrothermal method was used to synthesize W-Mo bimetallic sulfides (Mo1-xWxS2) from W-Mo alloy scrap, and a series of Mo 1-x W x S 2 nanoflower with different tungsten molybdenum ratios were prepared by simulating the leaching solution of the scrap. The products are three-dimensional, flower-like spherical structure assembled by interlacing nanosheets, exhibiting two crystal phases: 1 T and 2H. High piezoelectric catalytic activity was achieved by optimizing the crystal structure and atomic doping. The alloyed Mo 1-x W x S 2 nanoflowers with the 1 T phase concentration of 48.2% exhibits the highest piezoelectric catalytic activity, with degradation rates of 93.96%, 60.52%, and 65.67% for methylene blue (MB), rhodamine B (RhB), and tetracycline (TC), respectively. Additionally, we also elaborated on the influence of N, N-Dimethylformamide (DMF) on the morphology and crystal phase. The results indicate that the flower-shaped Mo 1-x W x S 2 exhibits a strong piezoelectric response. This work provides a novel and efficient approach for resource recycling, wastewater treatment and environmental catalytic applications.

Co-recovery of tungsten and lanthanum from photovoltaic tungsten-based busbars scrap by molten salt electrolysis SCIE
期刊论文 | 2025 | GREEN CHEMISTRY
Abstract&Keyword Cite

Abstract :

As a rare-earth reinforced tungsten alloy, photovoltaic tungsten-based busbars have been extensively employed in silicon production in recent years. The urgent issue at hand is the need to achieve the co-recovery of tungsten and lanthanum from photovoltaic tungsten wire scrap. In this study, the complete recycling of photovoltaic tungsten scrap is achieved for the first time through a brief molten salt electrolysis process, utilizing Na2WO4 as the electrolyte and tungsten wire scrap as the anode. The process involves a graphite crucible as the cathode, ensuring continuous contact with the product to prevent the oxidation of tungsten powder (W) to sodium tungsten bronze (NaxWO3) by Na2WO4 electrolyte. The corundum anode basket promotes the dissolution of La2O3 in the electrolyte to form La2(WO4)3. This compound actively participates in electrochemical reactions to facilitate the simultaneous production of W and La2O3. The regenerated tungsten powder possesses a uniform distribution of La2O3, making it a suitable raw material for the manufacture of photovoltaic tungsten-based busbars. Overall, this approach establishes a sustainable and environmentally friendly tungsten resource recycling ecosystem.

Full-component recycling with re-valorization from spent hydrodesulfurization catalyst: recovery of molybdates and synthesis of Ni2+ doped glass-ceramic SCIE

Abstract&Keyword Cite

Abstract :

Hazardous wastes from the production of cleaner fuels, spent hydrodesulfurization (HDS) catalysts, pose a threat to the environment and the sustainability of rare metal resources. However, conventional recovery approaches are limited by long processes, easy generation of waste liquids, and difficult reuse of recovery products. Herein, a SiO2-Na2O-B2O3-MgO-TiO2 glass phase extraction system was proposed for the full-component recycle from spent MoNi/gamma-Al2O3 catalysts to the materials, including the individual recovery of Mo and the synthesis of Ni2+-doped glass-ceramics. 96.7% of Ni and 99.8% of Al were extracted into the loaded glass in one step, while 95.3% of Mo was precipitated as molybdate and directly recovered with high separation factors (SFMo/Ni 594.8, SFMo/Al 8718.2) in one step. Moreover, the broadband near-infrared luminescence (1150 - 1700 nm) of glass-ceramics was triggered by Ni2+ in the octahedral crystal structure of Me3O5 (Me = Mg, Al, Ti) by melting-annealing-crystallization processes, which provided it the potential to be applied in tunable lasers and broadband optical amplifiers for the wavelength-division-multiplexing transmission systems. The Ni2+-doping mechanism was calculated using molecular dynamics simulations. This work emphasized the maximization of the reuse value for each metal resource from hazardous wastes while reducing the burden on the environment and achieving the recycling of rare metal resources with re-valorization.

Abstract&Keyword Cite

Abstract :

Bi2WxMo1_xO6/BiOBr composites was prepared by a one-pot hydrothermal method from the W-Mo alloy scrap as the raw material, and commercially available scientific reagents were used as raw materials to simulate different secondary resources. The products have a hydrangea-like structure, forming an orthorhombic crystal structure. Adjusting the W/Mo molar ratio (M(W):M(Mo)) of Bi2WxMo1_xO6/BiOBr was adjusted as 0:1, 1:3, 1:2.17, 1:2, 1:1, 3:1, and 1:0, and the results show that the Bi2W0.5Mo0.5O6/BiOBr composites prepared at M(W):M(Mo) = 1:1 has the best photocatalytic degradation performance for tetracycline (TC), with a removal rate of 93.33 % within 180 min and the removal rate remains at 85 % after four degradation cycles. The Bi2W0.5Mo0.5O6/BiOBr composites forms a type II heterojunction, which accelerates the separation of electrons (e_ ) and hole (h+), thereby enhancing the photocatalytic performance. This study show that it is feasible to prepare Bi2WxMo1_xO6/BiOBr composites from W-Mo alloy scrap. The process is simple and effective, providing a potential approach for the recycling and utilization of secondary resources.

Improvement in thermal stability of ODS-W alloy through formation of complex oxide dispersoids SCIE
期刊论文 | 2024 , 1002 | JOURNAL OF ALLOYS AND COMPOUNDS
Abstract&Keyword Cite

Abstract :

Thermal stability is a crucial issue for engineering application of tungsten, especially as plasma facing material in future fusion reactor. Two kinds of ODS-W alloys of W-0.5Y2O3 (WY) and W-0.5Y2O3-0.25Ti (WYT) were fabricated by ball milling and spark plasma sintering aiming at formation of oxide dispersoids with different crystallographic structures. Thermal stability of both ODS-W alloys was evaluated in terms of microhardness and microstructure evolution during isothermal aging at 1100 degrees C. Dispersoids of sesquioxide Y2O3 were identified in sintered WY, while pyrochlore Y2Ti2O7 with finer size and higher number density were developed in sintered WYT, resulting in higher bending strength of 1020 MPa and microhardness of 880 HV. Compared with sesquioxide Y2O3, complex dispersoids of pyrochlore Y2Ti2O7 exhibited much better coarsening resistance during isothermal aging at 1100 degrees C up to 100 h, where the intracrystalline and GB dispersoids maintained around 10 nm and 30 nm, respectively. The excellent coarsening resistance of complex Y2Ti2O7 with pyrochlore structure contributed to grain refinement and improved microstructure stability of WYT due to the effect of Zener drag.

Abstract :

As the primary candidate material for plasma facing components (PFCs) in fusion reactor, the serious brittleness of tungsten has become an urgent issue to be solved. In this work, a multi-doped W-Hf-Y2O3 2 O 3 alloy was prepared by high-energy ball milling and spark plasma sintering, aiming at improving its toughness through formation of complex oxide particles. Complex Y2Hf2O7 2 Hf 2 O 7 with pyrochlore structure were developed in the multi-doped WHY alloy due to dissolution and precipitation mechanism, which was confirmed by the combined characterization results of X-ray diffraction (XRD), electron probe microanalysis (EPMA) and transmission electron microscope (TEM). Complex oxide particles of Y2Hf2O7 2 Hf 2 O 7 with average size of 38.8 nm were densely distributed in the alloy. The formation of complex Y2Hf2O7 2 Hf 2 O 7 particles with nano-scale size not only consumed the impurity of oxygen, but also played a critical role in grain refinement because of Zener pinning effect. Improvement in mechanical properties of the multi-doped WHY alloy was then achieved, and the fracture toughness and compressive strength reached 19.7 MPa center dot m1/2 center dot m 1/2 and 2223.4 MPa, respectively.

Abstract :

Tungsten trioxide is a promising photoelectric material owing to its abundant structures and unique properties, but the serious photogenerated charge recombination limits its photocatalytic and photoelectrochemical performance. Herein, 0D Cu2O was anchored onto 3D WO3 in-situ via a facile adsorption-ascorbic acid reduction method at room temperature. The coupling of WO3 with Cu2O produces improved charge separation efficiency, thereby the photocatalytic degradation rate and transient photocurrent of optimal WO3/Cu2O are 2.7 and 1.6 times higher than those of WO3, respectively. The enhanced performance is ascribed to the formation of a p-n heterojunction, which was demonstrated by experimental characterizations and theoretical calculation.

Abstract :

Separation and recovery of molybdenum (Mo) with high concentrations from spent catalysts is a strategy for avoiding the environmental footprint by metal mining and the disposal of hazardous wastes, while alleviating resource shortage. In this paper, a method for constructing a binary (SiO2-Na2O)/ternary (SiO2-Na2O-B2O3) glass phase extraction (GPE) system to selectively extract the impurity metal ions from spent catalysts as well as simultaneously separate and recover Mo is presented. Based on experimental studies and classical molecular dynamics simulations, compared with the binary glass network, 99.4% of Al3+ and Ni2+ in spent catalysts were extracted in a more stable tetra-coordinated form at a lower melting temperature (1200 degrees C) by the ternary GPE system introducing B2O3, accompanied by Na2MoO4 precipitated as the recovery product. The recovery efficiency of Mo was 98.1%, realizing an efficient separation and short-process recovery. Moreover, the separation of Na2MoO4 melt and glassy liquid during the melting process was visually observed online. Therefore, this approach of constructing glass GPE systems for the one-step separation of metals during the melting process is expected to contribute to the sustainable supply of critical metals.
