Cuprous oxide (Cu2O) suffers from severe electron-hole pairs recombination, instability and low photocatalytic degradation efficiency, though it has been considered as an excellent visible light photocatalyst. The incorporation of the Cu2O with other photocatalysts can address these problems. Herein, unique Cu2O@ polydopamine (PDA) nanospheres are prepared by a simple photo-reduction approach. Due to the synergistic effects of the Cu2O and PDA semiconductors, the Cu2O@PDA nanospheres composite possesses enhanced photocatalytic activity and extended life time for the degradation of the methyl orange under visible light irradiation.
