Abstract ：
This study is about anammox bacteria's physiologicalaptitudes, providing insights into applying solar energy for enhancedwastewater treatment. This study introduced photogenerated electrons into theanammoxsystem by coupling them to a g-C3N4 nanoparticlephotocatalyst. A high nitrogen removal efficiency (94.25%) was achieved,exceeding the biochemical limit of 89% imposed by anammox stoichiometry.Photogenerated electrons boosted anammox metabolic activity by empoweringkey enzymes (NIR, HZS, and WLP-related proteins) and triggered rapidalgal enrichment by enhancing the algal Calvin cycle, thus developingmultiple anammox-algae synergistic nitrogen removal processes.Remarkably, the homologous expression of cbb3-type cytochrome c oxidase(CcO) in anammox bacteria was discovered and reported in this studyfor the first time. This conferred aerobic respiration capabilityto anammox bacteria and rendered them the principal oxygen consumerunder 7.9-19.8 mg/L dissolved oxygen, originating from algalphotosynthesis. Additionally, photogenerated electrons selectivelytargeted the cb1 complex and cbb3-type CcO as activation sites whilemobilizing the RegA/B regulatory system to activate the expressionof cbb3-type CcO. Furthermore, cbb3-type CcO blocked oxidative stressin anammox by depleting intracellular oxygen, a substrate for reactiveoxygen species synthesis. This optimized the environmental sensitivityof anammox bacteria and maintained their high metabolic activity.This study expands our understanding of the physiological aptitudesof anammox bacteria and provides valuable insights into applying solarenergy for enhanced wastewater treatment.

Abstract ：
Two-dimensional carbon-based materials have great potential for electrocatalysis. Herein, we screen 12 defective and doped C3N nanosheets by evaluating their CO2RR and NRR activity and selectivity vs. the HER based on density functional theory calculations. The calculation results suggest that all 12 C(3)Ns can enhance CO2 adsorption and activation. And P-N-V-C-C3N is the best electrocatalyst for the CO2RR towards HCOOH with U-L = -0.17 V, which is much more positive than most of the reported values. B-N-C3N and P-N-C3N are also good electrocatalysts that promote the CO2RR towards HCOOH (U-L = -0.38 V and -0.46 V). Moreover, we find that Si-C-C3N can reduce CO2 to CH3OH, adding an alternative option to the limited catalysts available for the CO2RR to CH3OH. Furthermore, B-C-V-C-C3N, B-C-V-N-C3N, and Si-C-V-N-C3N are promising electrocatalysts for the HER with |Delta G(H*)| <= 0.30 eV. However, only three C(3)Ns of B-C-V-C-C3N, Si-C-V-N-C3N, and Si-C-V-C-C3N can slightly improve N-2 adsorption. And none of the 12 C(3)Ns are found to be suitable for the electrocatalytic NRR because all the Delta e(NNH*) values are larger than the corresponding Delta G(H*) values. The high performance of C(3)Ns in the CO2RR stems from the altered structure and electronic properties, which result from the introduction of vacancies and doping elements into C3N. This work identifies suitable defective and doped C(3)Ns for excellent performance in the electrocatalytic CO2RR, which will inspire relevant experimental studies to further explore C(3)Ns for electrocatalysis.

Abstract ：
Over the few decades, photochemistry has received great attention and become a powerful tool in organic synthesis. Heterogeneous photocatalysts present complementary advantages in production, separation, catalyst recycling, and stability compared to the traditional homogeneous photocatalysts. In this review, we choose C-N bond formation as a typical coupling reaction and summarize the development of a heterogeneous catalytic system and its advantages. Titanium dioxide, semiconductor quantum dots, covalent organic frameworks, and carbon nitrides are discussed in detail as important heterogeneous photocatalysts. The combination and electron transfer pathway between heterogeneous catalysts and transition-metal catalysts are the focus of this review. These advances are not only limited to the C-N coupling, but also extend to other coupling reactions.

Abstract ：
Slow charge transfer and carrier recombination are key issues in photocatalytic reactions. The current solution is to load small-sized cocatalysts onto large-sized photocatalysts. Here a new strategy is pro-posed. Small-sized photocatalysts of cadmium sulfide (CdS) nanosheets are grown onto large-sized cocat-alysts of N-doped amorphous carbon (a-CN) to construct CdS @ a-CN photocatalysts. Photoluminescence spectra and transient photocurrent demonstrate that optimized CdS @ a-CN shows effective charge sep-aration compared with CdS. The corresponding photocatalytic H2 yield of optimized CdS @ a-CN is-244 lmol, which is 3.6 times higher than that of CdS. Besides, the hydrogen yield for CdS under visible-light irradiation is significantly improved from-44 lmol to-217 lmol for the optimized CdS @ a-CN. Our design strategy provides an effective way to construct photocatalytic systems with outstand-ing photocatalytic performance.(c) 2022 Published by Elsevier Inc.

Abstract ：
Fluorescent carbon dots are a novel type of nanomaterial. Due to their excellent optical properties, they have extensive application prospects in many fields. Studying the formation process and fluorescence mechanism of CDs will assist scientists in understanding the synthesis of CDs and guide more profound applications. Due to their conjugated structures, aromatic compounds have been continuously used to synthesize CDs, with emissions ranging from blue to NIR. There is a lack of a systematic summary of the formation process and fluorescence mechanism of aromatic precursors to form CDs. In this review, the formation process of CDs is first categorized into three main classes according to the precursor types of aromatic compounds: amines, phenols, and polycyclics. And then, the fluorescence mechanism of CDs synthesized from aromatic compounds is summarized. The challenges and prospects are proposed in the last section.

Abstract ：
To perform the electrochemical nitrogen reduction reaction (NRR) under milder conditions for sustainable ammonia production, electrocatalysts should exhibit high selectivity, activity, and durability. However, the key restrictions are the highly stable N N triple bond and the competitive hydrogen evolution reaction (HER), which make it difficult to adsorb and activate N-2 on the surface of electrocatalysts, leading to a low ammonia yield and Faraday efficiency. Inspired by the enzymatic nitrogenase process and using the Fe-Mo as the active center, here we report supported Fe2Mo3O8/XC-72 as an effective and durable electrocatalyst for the NRR. Fe2Mo3O8/XC-72 exhibited NRR activity with an NH3 yield of 30.4 mu g.h(-1).mg(-1) (-0.3 V) and a Faraday efficiency of 8.2% (-0.3 V). Theoretical calculations demonstrated that the electrocatalytic nitrogen fixation mechanism involved the Fe atom in the Fe2Mo3O8/XC-72 electrocatalyst acting as the main active site in the enzymatic pathway (*NH2 ->*NH3), which activated nitrogen molecules and promoted the NRR performance.

Abstract ：
Although the carbon nitrides copolymers (CNs) exhibit enhanced photocatalytic performance, the essential reason remains unclear. Systematic research on incorporated molecules with structure similarity but different natures helps gain a fundamental understanding of CNs photocatalyzed reactions. A series of dihydroxyl-N-heterobenzene with a different number of N atoms and at different positions of the six-member ring are selected for constructing CNs. Structural identifications demonstrate N-heterobenzene links with heptazine of CN networks at the hydroxyl sites in the synthesized CNs. The theoretical calculation reveals that the electrostatic potential (ESP) of asymmetry pyridine strongly induces the HOMO and LUMO separation, located at different heptazine units. This is significantly different from the traditional heterojunction or D-A system. A kinetics study of CNs/triethanolamine system for photocatalysis was carried out with photovoltage spectra of CNs series. The linear-relationship between extraction charge and H-2 generation rate suggests a Volmer-Heyrovsky mechanism which is commonly acknowledged for electrocatalysis but barely mentioned in photocatalysis.

Abstract ：
It is a challenging task to overcomes the bottleneck of N2 adsorption and activation in N2 reduction reaction (NRR). Regulating the catalyst surface electronic state is treated as a potential strategy to prevail over the barrier. Here, Incorporating Fe as a dopant in the TiO2 nanoparticles can generate oxygen vacancies and dopant energy levels, promoting the adsorption and activation of N2 molecules. F surface modification induces Fe (III) in the high spin state and upshifts the dopant energy level. That facilitates Fe 3d electrons backdonation to N 1ag* orbital promotes the activation of N2 molecule and reduces the limiting potential of NRR. Therefore, F-Fe: TiO2 electrocatalyst achieved the highest Faradaic efficiency and maximum NH3 production rate of 27.67% and 27.86 mu g h-1 mgcat. -1 at -0.5 V v.s. reversible hydrogen electrode. This work provides deep insights into the design surface electronic state of catalyst toward efficient N2 to NH3 conversion.

Abstract ：
The solar H-2 generation directly from natural seawater is a sustainable way of green energy. However, it is limited by a low H-2 generation rate even compared to fresh water. In this report, TiO2 is chosen as a model photocatalyst to disclose the critical factor to deteriorate the H-2 generation rate from seawater. The simulated seawater (SSW), which is composed of eight ions (Na+, K+,Ca2+, Mg2+, Cl-, Br-, SO42-, and CO32-), is investigated the effect of each ion on the H-2 production. The results indicate that all ions have a negative effect at the same concentration as in the seawater except Br-. The CO32- has the most serious deterioration, and the H-2 production rate lowers near 40% even at [CO32-] of 1.5 mmol- L-1. The H-2 production rate can be recovered to 85% if the CO32- is excluded from the SSW. To understand the reason, the zeta potential of the TiO2 treated with different ions aqueous solution reveals that the zeta potential decreases when it is treated with CO32- and SO42- due to they can adsorb on the surface of TiO2 nanoparticles. Fourier transform infrared (FTIR) and thermogravimetric analysis-mass spectroscopy (TGA-MS) further confirm that the adsorbed ion is mainly from CO32-. Since the pH of seawater is about 8.9 between pK(a1) (6.37) and pK(a2) (10.3) of H2CO3, the CO32- should exist in the form of HCO3- in the seawater. We proposed a simple method to remove the adsorbed HCO3- from the TiO2 surface by adjusting the pH below the pK al . The results indicate that if a trace amount of HCI (adjusting pH similar to 6.0) is added to the SSW, the H-2 production rate can be recovered to 85% of that in pure water.
