Abstract

A novel inorganic-organic Se rich-ZnSe(en)_0.5 red-brick (ZnSe(en)_0.5 RB) was developed on Zinc (Zn) foil through a low-temperature solvothermal synthesis. The structure evolution and growth mechanism of ZnSe(en)_0.5 RB were systematically proposed at 80 °C by varying the solvothermal times (2−12 h). In the reaction system, adsorption of reduced Se²⁻ in presence of ethylenediamine ((en)_0.5) induced the red-brick (RB) color to ZnSe(en)_0.5. Furthermore, Cd²⁺ ion-exchange strategy was adopted for converting ZnSe(en)_0.5 RB into dual nanoarchitecture photoelectrode (ZnO-Zn_1-xCd_xSe). The optimum ZnO NR-Zn_1-xCd_xSe NP 160 photoelectrode converted from ZnSe(en)_0.5 RB-12 exhibited a photocurrent density of 13.14 mA·cm^-2 at -0.2 V vs. Ag/AgCl with 237.79 μmol·cm⁻² hydrogen evolution over 3 h. The enhanced photocurrent performance was due to the effective light absorption, and the prolonged recombination lifetime. The charge separation and transport mechanisms during photoelectrochemical hydrogen production were also investigated in detail.
