英文摘要 | cucro2 delafossite was prepared by the solid-state reaction between cr2o3 and cu2o at high temperature (900-1100 a degrees c). the materials were characterized by xrd, x-ray photoelectron, raman and uv-vis spectroscopy and transmission electron microscopy. the visible light absorption of the p-type semiconductor increased with increasing calcination temperature. first principles density functional theory calculations were used to compute the density of states and distinguish between cr3+ d-d transitions and the charge separation electron transitions, which cannot be distinguished in cucro2 by uv-vis spectroscopy. photocathodes were prepared by depositing the as-prepared cucro2 on an fto substrate by electrophoresis. the resulting cathodic photocurrents under visible light irradiation increased with increasing calcination temperature. cucro2 is a photostable semiconductor unlike cu2o. photocatalytic h-2 production in ethanol/water mixtures shows that the resulting materials are active in water splitting. co-catalysts substantially increase the activity, the most preferred one is pt with an order of magnitude increase in performance. |
