Photocatalysis is a potential strategy to solve energy and environmental problems. The development of new sustainable photocatalysts is a current topic in the field of photocatalysis. ZnInS, a visible light-responsive photocatalyst, has attracted extensive research interest in recent years. Due to its suitable band gap, strong chemical stability, durability, and easy synthesis, it is expected to become a new hot spot in the field of photocatalysis in the near future. This mini-review presents a comprehensive summary of the modulation strategies to effectively improve the photocatalytic activity of ZnInS such as morphology and structural engineering, defects engineering, doping engineering, and heterojunction engineering. This review aims to provide reference to the proof-of-concept design of highly active ZnInS-based photocatalysts for the enhanced hydrogen evolution reaction.

The conversion of solar energy into chemical energy or high-value chemicals has attracted considerable research interest in the context of the global energy crisis. Hydrogen peroxide (HO) is a versatile and powerful oxidizing agent widely used in chemical synthesis and medical disinfection. HO also serves as a clean energy source in fuel cells, generating electricity with zero-carbon emissions.

The preparation strategy is the important factor to obtain the effective photocatalyst, and the thermal decomposition could be used to prepare photocatalysts with high crystallinity and photoactivity. In this paper, thermal decomposition method was used to deposit CuO nanoparticles on TiO nanotube arrays (TiO NTs), and the TiO NTs/CuO exhibited remarkably high visible light absorption and photoelectrocatalytic performances toward dye degradation and Cr(VI) reduction. The potential degradation pathway and toxicities of rhodamine B (RhB) dyes and intermediates were investigated.

In flow-through reactors, the photodegradation rate can be improved by enhancing contact and increasing the photocatalyst loading. Both can be attained with a higher surface-to-volume ratio. While previous studies focused on thin membranes (30 - 130 µm) with small pore sizes of 20 - 650 nm, this work employed poly(tetrafluoroethylene) (PTFE) supports, of which pore sizes are in the order of 10 µm, while the porosities and thicknesses are variable (22.

Porous supramolecular crystalline materials (PSCMs), usually including hydrogen-bonded organic frameworks (HOFs), π frameworks, and so on, can be defined as a type of porous supramolecular assemblies stabilized by hydrogen-bonding, π-π stacking and other non-covalent interactions. Given the unique features of mild synthetic conditions, well-defined and tailorable structures, easy healing and regeneration, PSCMs have captured widespread interest in molecular recognition, sensor, gas storage and separation, and so on. Moreover, they currently emerge as promising photocatalysts because it is readily to endow PSCMs with photo-function, and the hydrogen-bonding and π-π stacking can serve as electron transfer channels to boost photocatalytic activity.

In this work, a series of new crystalline three-dimensional covalent organic frameworks (3D COFs) based on [8+4] construction was designed and successfully realized efficient photocatalytic acetylene (C2H2) hydrogenation to ethylene (C2H4). By regulating the hydrogen-localization transfer effect in these 3D COFs,the Cz-Co-COF-H containing cobalt glyoximate active centers exhibited excellent C2H2-to-C2H4 performance, with an average C2H4 yield of 1755.33 μmol g-1 h-1 in pure C2H2, also showed near 100% conversion of C2H2 in 1% C2H2 contained crude C2H4 mixtures (industry-relevant conditions), and finally obtain polymer grade C2H4.
