Abstract:

Among the various non-precious metal catalysts that drive hydrogen evolution reactions (HERs) and dyesensitized solar cells (DSSCs), transition metal selenides (TMSs) stand out due to their unique electronic properties and tunable morphology. Herein, the multicomponent selenide CuSe-Co 3 Se 4 @VSe 2 was successfully synthesized by doping with metal element vanadium and selenization on the copper-cobalt carbonate hydroxide (CuCo-CH) template. CuSe-Co 3 Se 4 @VSe 2 exhibited the dandelion-like cluster structure composed of hollow nanotubes doped with VSe 2 nanoparticles. Due to the unique structure and the synergistic effect of various elements, CuSe-Co 3 Se 4 @VSe 2 showed excellent alkaline HER and DSSC performances. The DSSC based on CuSeCo 3 Se 4 @VSe 2 exhibited an impressive power conversion efficiency (PCE) of 9.64 %, which was much higher than that of Pt (8.39 %). Besides, it possessed a low HER overpotential of 76 mV@10 mA cm-2 and a small Tafel slope of 88.9 mV dec- 1 in 1.0 M KOH.
