“…2D/2D heterojunctions are still the most commonly used method for enhancing photocatalytic activity. Considering future practical applications, the combination with traditional and economical catalysts such as g-C 3 N 4 , TiO 2 , and CdS is still 180 Later, the team successfully prepared type-II p(Cu x Se y )/n(g-C 3 N 4 ) heterojunctions, which showed stronger light absorption capacity and stronger photogenerated carrier separation ability. 181 In addition to the combination with traditional 2D materials, Cu 9 S 5 @UiO-66-NH 2 composites also exhibit excellent Fenton-like photocatalytic activity for Congo red and Rhodamine B.…”

With the increasing variety of Cu-based semiconductor nanomaterials and the development of synthesis technology, the crystal shape and morphology of semiconductor materials have become controllable factors. Due to their low price, abundant reserves, and suitable band gap, Cu-based semiconductor nanomaterials have bright application prospects for the treatment of photocatalytic environments. A comprehensive summary of the basic theory and research progress of Cu-based semiconductor nanomaterials, such as crystal design, morphology control, and photocatalytic modification strategies and mechanisms, is indispensable. However, a comprehensive review of this aspect has not been reported recently. This review summarizes the synthetic methods of copper oxides (CuO, Cu 2 O), copper sulfides (CuS, Cu x S, Cu 2 S), copper selenides (CuSe, Cu 2−x Se, Cu 2 Se), as well as other novel Cu-based semiconductor nanomaterials such as CuFe 2 O 4 , Cu 3 N, Cu 5 V 2 O 10 , CuCo 2 O 4 , CuWO 4 , Cu 3 P, and the application strategies and mechanisms in photocatalytic removal of pollutants, photocatalytic hydrogen evolution, and photocatalytic reduction of CO 2 . The summary of synthesis methods and crystal surface control is beneficial for the preparation of better catalysts. We firmly believe that this review can provide valuable information for the further development of Cu-based semiconductor nanomaterials.

“…In this stage, the product was collected washed and finally dried in open atmosphere. Further development was made by Nouri et al [ 69 ] using a much precise and time‐efficient route to construct binary copper selenide nanostructures (Se/Cu:0.6–1.5) by dissolving 0.005 m Cu(NO 3 ) 2 •3H 2 O and glycine amino acid in 50 mL of DI water followed by loading 0.005 m Se to the obtained precursor solution. Another solution was prepared by dissolving NaBH 4 in 50 mL of DI water and injected in the first solution under constant stirring at room temperature.…”

Recent Advancements in the Synthetic Mechanism and Surface Engineering of Transition Metal Selenides for Energy Storage and Conversion Applications

Novel catalytic materials are under investigation to find convincing energy alternatives. In this context, transition metal selenides (TMSes) are found to be feasible, ecofriendly, and effective electrocatalysts with futuristic characteristics. A deep and comprehensive investigation on metal selenides for energy conversion and storage application is summarized in this review article. Different methods such as hydrothermal, solvothermal, coprecipitation, hot injection, successive ionic layer adsorption reaction, polyol, and others can be used for the synthesis of metal selenides based electrocatalysts, with different morphologies and compositions. The morphology of metal selenides is strongly controlled by factors such as reaction time, temperature, pH of the reaction medium, and surfactant. The electrochemical applications of metal selenides are governed by morphology, active spots for reaction, surface engineering, and confinement. It is concluded that TMSes deliver high performance with large surface area, which is possible due to their porous or 3D morphology. The TMSes with multimetal or with doping metal/nonmetals perform better compared to single atoms. It is concluded that the reaction mechanism of hydrogen evolution reaction and oxygen evolution reaction is a primary tool to better understand the system to develop more efficient catalysts for practical application.
