“…CuSe is widely used in the photoFenton system and also exhibits certain degradation activity under dark state conditions. Liu et al prepared CuSe(Cu 2 Se)/g-C 3 N 4 using Cu 2 O as a template, and the degradation rate of MB in the photoFenton system could reach 98.3% in 60 min . Surprisingly, it can also degrade MB to some extent under dark state conditions.…”

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.

Rational designing of multicomponent selenide‐based composites such as Co9Se8/Ni3Se4/Cu2Se (CNCD) is synthesized through a simplistic hydrothermal method. Several standard characterization techniques are utilized to study the structural, morphological and elemental features of the obtained samples with varying selenide content. Both electrochemically and photocatalytic performance are amplified at an optimized selenide content denoted as CNCD‐0.5 due to its favourable characteristics and morphology. From the electrochemical measurements, the battery‐type performance of the CNCD‐0.5 is established from the well‐distinguished redox peaks. For practical utility, the assembled CNCD‐0.5 (+) // AC (−) device delivered an energy density of 35.97 Wh kg−1 at a power density of 1210.86 W kg−1 with a capacity retention of 91% for 5000 cycles of uninterrupted charge–discharge. Further, the photo‐Fenton‐based degradation experiments are assessed by demineralization of cationic RhodamineB (RhB) and anionic Tartrazine (Tz) dye using H2O2 with the minimal dosage of catalyst (0.3 g L−1). At an optimized concentration of H2O2, CNCD‐0.5 can degrade 97.14% of RhB (40 mg L−1) and 94.77% of Tz (40 mg L−1) for 120 min of visible‐light illumination. Such designing of multinary metal selenides‐based nanocomposites holds promising potential for multifunctional applications due to the synergistic advancement in the composite properties.
