报告摘要：
Developing advanced photoanode structure to decrease the charge recombination is a mandatory requirement to enhance charge separation and transfer for photoelectrochemical reaction. The hybrid Bi2MoO6@Bi2Mo2O9 by one-step SILAR method achieves enhanced charge separation (20.5%) and oxidation (54.6%) kinetics due to the matched energy band. An interfacial engineering design of quaternary layered Bi2S3/Bi2Mo2O9/Bi2S3/Bi2Mo2O9 by SILAR method constructed pn/Z-scheme/pn system. The double p-n junctions reinforce the charge separation when the semiconductor absorbs photons. The third ultrathin interlayer Bi2Mo2O9 sandwiched between two Bi2S3 layers plays as a carriers’ tunneling channel, which can accelerate the directional flowing of electrons in bi-layer Bi2S3. This optimized structure exhibits a remarkable charge separation efficiency of 41%. CIMPS dynamic analysis shows its lowest charge transport time (5 μs).
