摘要

Herein, dual nanostructured ZnO nanorod (NR)-Zn1-xCdxS porous nanosheet (PNS) photoanodes were produced on a zinc foil through cation exchange reaction of inorganic-organic hybrid ZnS(en)(0.5) nanosheets. ZnS(en)(0.5) NS's photoanodes have been synthesized via a facile solvothermal method followed by a series of cadmium (Cd2(+)) ion-exchange using various ion-exchange reaction times and temperatures. During Cd2(+) ion-exchange, the Zn1-xCdxS PNS and a new type of vertically aligned ZnO NR were subsequently grown on the zinc foil substrate. The different exposed surfaces of the vertically aligned hexagonal ZnO NR and Zn1-xCdxS PNS photoanodes contribute to appropriate morphology, effective light harvesting, and efficient charge separation in ZnO-NR-Zn1-xCdxS PNS160C. The optimum ZnO NR-Zn1-xCdxS PNS160C photoanode contributed the highest photocurrent density of 6.60 mA center dot cm(-2) and hydrogen production of 250.65 mu mol center dot cm(-2) at 0 V vs. Ag/AgCl. Finally, the charge transfer mechanism in the optimum photoanode is discussed in detail.
