摘要：

A dual-photoelectrode PFC system was constructed using an excellent SnO2/BiOBr/MoS2 as a photoanode and copper oxide/copper as a photocathode for the first time. The appropriate interfacial contact and outstanding photoelectrochemical activity of the photoanode can be attributed to SnO2 hole-blocking layer. It is not only employed as a conductive scaffold for BiOBr/MoS2 but also provided less tendency for charge transport loss. In addition, the by-product Bi2S3 acts as a sensitizer due to its broad absorption spectrum (similar to 800 nm) to increase light harvesting. The resulting SnO2/BiOBr/M...
