Abstract ：
Constructing homojunction hierarchical nanostructures with intimate contact and favorable carriers separation is an effective and challenging strategy to obtain efficient photocatalysts. We here report an immobilized WO3/ W18O49 homojunction photocatalyst with W18O49 branches growing out of WO3 trunks. Under simulated sunlight irradiation, the optimal WO3/W18O49 composite exhibits enhanced adsorption and photocatalytic performance, which are 10.69 and 3.61 times higher than those of WO3, respectively. The superior performance is ascribed to the well-distributed trunk-branch structure, surface charge and effective charge transfer and separation in the homojunction composites, which was verified by experimental characterizations and the density functional theory (DFT) calculation. This work provides a solid foundation for further study and may give rise to the design of other photocatalysts.

Abstract ：
In this study, spent WO3/V2O5-TiO2 catalysts used for selective catalytic reduction were treated by a hydrometallurgical process to comprehensively recover valuable metallic elements, such as W, V, and Ti. Al and Si impurities were preferentially removed by selective microwave-assisted alkali leaching. W and V were leached by enhanced high-pressure leaching with efficiencies estimated at 95% and 81%. The leaching of W and V followed the nuclear shrinkage model controlled by the combination of product layer diffusion and interfacial chemical reaction. A synergistic extraction was applied to separate W and V using an extractant mixture of di-(2-ethylhexyl)phosphoric acid P204 and the primary amine N1923. The extraction efficiencies of V and W reached 86.5% and 6.3%, respectively, with a separation coefficient (V/W) of 95.30. The product was precipitated after extraction to yield ammonium paratungstate (APT) and NH4VO3. The TiO2 catalyst carrier residue meets commercial specifications for reuse. This comprehensive recovery process with the characteristics of high-pressure leaching and synergistic extraction realizes the resourceful utilization of the spent catalysts.

Abstract ：
Photocatalysis has become an increasingly popular method to treat pharmaceuticals and personal care products (PPCPs) in a water matrix due to its green and energy-saving nature. However, the development of highefficiency catalysts to remove such refractory organic pollutants still faces many challenges. Herein, an urchin-like composite, Bi/W18O49, was designed and prepared via solvothermal process followed by magnetron sputtering method. The photocatalytic performance of Bi/W18O49 for PPCPs removal proved to be superior under red light (610 nm, 1.23E4 lm) compared with pure WO3 or W18O49, due to better light absorption property and frequency matching between the stronger plasmon resonance (dual-LSPR effect) and incident light irradiation. Thorough experiments were conducted to identify the unique properties of Bi/W18O49, and they demonstrated that the composite state contained plenty of oxygen vacancies and the dual-LSPR effect was vital to the efficient removal for pollutants, as the effect guarantees OV level, hot electron transfer, stable light response ability and more positive potential. The photocatalytic results show that the removal efficiency of trimethoprim, acetaminophen, and tetracycline by Bi/W18O49 could reach 93 %, 87 %, and 62 %, respectively. Combined with density functional theory (DFT) calculations and analysis, trapping tests, and LC-MS measurement, the degradation pathways of those pollutants were described in detail as well. Additionally, different influencing factors such as the concentration of catalyst and pollutants, pH of the solution, various inorganic and organic species were comprehensively investigated, and the reusability and stability property of the product performed well. To the best of our knowledge, this is the first time such Bi/W18O49 composite was prepared and applied in treating PPCPs, representing a new strategy for effective wastewater treatment via the construction of LSPR materials.

Abstract ：
含钼合金具有较高的硬度、优异的耐磨耐腐蚀性能和催化析氢性能,作为涂层和电极材料在金属防护、电解水制氢等领域得到了广泛的应用.电沉积法具有沉积速度快、沉积镀层致密及产物种类多等优点,是制备含钼合金的重要技术之一.早期电沉积法用于制备二元含钼合金,对其电沉积工艺及机理的研究较为深入,但通过调整工艺参数的方法对二元含钼合金性能的提高仍旧有限.为了改善二元含钼合金的性能,添加合金元素制备多元含钼合金以及添加粒子制备粒子掺杂含钼合金成为近年的研究热点和趋势.多元含钼合金中添加的元素主要包括C、Fe、P、W、Cr等,能有效改善其不同方面的性能.改善催化析氢性能的元素有C、Zn、Sn、S、Fe、P等,其机理在于它们与铁族元素和钼元素能产生协同作用;提高显微硬度和耐磨耐腐蚀性能的元素有W、Cr、P等,其机理在于它们能改变合金结构,造成晶格畸变.粒子掺杂含钼合金中添加的粒子主要有ZrO2、TiO2、SiC、TiN等,能显著改善合金的显微硬度和耐磨耐腐蚀性能,这是因为纳米颗粒能在合金基质中弥散分布,起到细化晶粒及阻碍位错运动的作用.近两年,磁场、超声波辅助电沉积的工艺被大量应用到粒子掺杂含钼合金的制备中,实现了合金性能与电流效率的双提升.本文总结了近年来电沉积法制备含钼合金的研究进展,分别对二元含钼合金(如Ni-Mo和Co-Mo合金)、三元含钼合金(如Ni-Mo-Zn和Co-Mo-P合金)以及粒子掺杂合金(如Ni-Mo-ZrO2和Co-Mo-TiO2合金)的电沉积制备工艺、原理及合金性能等进行介绍,总结归纳了合金元素以及粒子掺杂改善含钼合金的异同点,分析了目前电沉积法制备含钼合金存在的问题及发展前景,以期为制备出性能更优异、应用更广泛的含钼合金提供参考.

Abstract ：
The Al-containing particles in ODS alloys with Al addition usually exhibit relatively large size, and inevitably result in a limited improvement in mechanical properties. In this paper, W-Al-Y2O3 alloy was prepared by a two-step sintering process to refine the Al-containing particles. Microstructure evolution of dispersoid particles was characterized by scanning electron microscope (SEM), electron probe microanalysis (EPMA) and transmission electron microscopy (TEM). During the first holding step at 1000 degrees C, the dissolved Al precipitated directly from W matrix, where the formed gamma-Al2O3 particles were nano-sized and developed a coherent relationship with W matrix. This coherent relationship hindered transformation of gamma-Al2O3 into submicron-sized alpha-Al2O3. Moreover, the nano-sized gamma-Al2O3 contributed to formation of fine Y3Al5O12 dispersoid particles with the sintering tem-perature further increased to 1600 degrees C. 71% of the dispersoid particles were distributed within grains and most of them were nano-sized gamma-Al2O3 and Y3Al5O12, giving a fine grain size of 0.49 mu m. Due to the refined micro-structure, the compressive strength and microhardness of W-Al-Y2O3 alloy reached 2545.9 MPa and 787.8 HV, respectively.

Abstract ：
In this study, LiNi0.8Co0.15Al0.05O2@x%Al(2)O(3-)coated cathode materials were regeneratively compounded by the solid-phase sintering method, and their structural characterization and electrochemical performance were systematically analyzed. The regenerated ternary cathode material precursor synthesized by the co-precipitation method was roasted with lithium carbonate at a molar ratio of 1:1.1, and then completely mixed with different contents of aluminum hydroxide. The combined materials were then sintered at 800 & DEG;C for 15 h to obtain the regenerated coated cathode material, LiNi0.8Co0.15Al0.05O2@x%Al2O3. The thermogravimetry analysis, phase composition, morphological characteristics, and other tests show that when the added content of aluminum hydroxide is 3%, the regenerated cathode material, LiNi0.8Co0.15Al0.05O2@1.5%Al2O3, exhibits the highest-order layered structure with Al2O3 coating. This material can better inhibit the production of Ni2+, and improve material structure and electrochemical properties. The first charge-discharge efficiency of the battery assembled with this regenerated cathode material is 97.4%, a 50-cycle capacity retention is 93.4%, and a 100-cycle capacity retention is 87.6%. The first charge-discharge efficiency is far better than that of the uncoated regenerated battery.

Abstract ：
Tungsten trioxide has attracted extensive attention for photocatalytic applications owing to its unique structure and intrinsic merits; however, the small specific surface area and rapid electron-hole recombination still limit its adsorption and photocatalytic efficiency. Herein, WO3 center dot 0.33H(2)O/g-C3N4 nanocomposite photocatalysts were designed and constructed using a facile low temperature hydrothermal method. The interaction between 1D WO3 center dot 0.33H(2)O nanorods and 2D g-C3N4 nanosheets produces a heterojunction with enhanced adsorption and photocatalytic degradation performance towards methylene blue pollutant. It is found that the synergistic effect of the surface charge and specific surface area significantly enhances the adsorption capacity which can be up to 23 times higher than that of WO3 center dot 0.33H(2)O, and the optimal photocatalytic activity is 3.67 and 1.70 times higher than that of pristine WO3 center dot 0.33H(2)O and g-C3N4, respectively.

Abstract ：
This study examined the possibility of deep significance for the reduction of low-valence tungsten to inhibit disproportionation reactions in various molten alkali chlorides. Electrolysis and electrochemical tests of tungsten carbide were carried out in molten LiCl, LiCl-KCl, NaCl-KCl, NaCl-CsCl, and KCl-CsCl. One finding was that the reduction valence of tungsten ions decreased as the radius of the solvent alkali ion increased. This phenomenon may be viewed from the dissolution of tungsten carbide and the existence and deposition of tungsten ions. The mechanism of tungsten ion reduction and the stable configuration of tungsten ion groups were confirmed via a detailed study of the computational calculation. The increase in the radius of the solvent alkali ion was conducive to the dissolution of tungsten from tungsten carbide in the form of low valence state. Other results also indicated that W(ii) ion groups first deposited on the cathode. They had the advantages of smaller coordination numbers and faster diffusion combined. Morphological and composition analysis results of the products are also presented.

Abstract ：
A method of improving the oxidation resistance of Cantor alloy through microstructure tailoring was revealed. Samples with distinctive microstructures were achieved by different annealing treatments on the cold-rolled Cantor alloy. Oxidation test was then carried out on the various annealed samples at 800 degrees C for 24 h in air. The oxidation behavior was evaluated in terms of oxidation rate, surface and cross-section microstructure characterization. Although stratified oxide layers including outer Mn2O3 and inner Cr2O3 were observed in all the annealed samples, the thickness of Mn2O3 and Cr2O3 layers was different. Also, the samples exhibited different oxidation rates. The results indicate that the oxidation resistance of various annealed samples is closely related with grain size as well as twin density.
