CuO x /g-C 3 N 4 /MnO x heterostructure has been fabricated by one-step photodeposition approach. The spatially separated CuO x and MnO x dual cocatalysts restrain the recombination of photoinduced carriers and improve the CO 2 photoreduction performance.
A novel lotus seedpod shaped Cu2O/g-C3N4 p–n heterojunction composite was fabricated by in situ filling the g-C3N4 framework with Cu2O hollow nanospheres for efficient photocatalytic hydrogen evolution.
