The MoS/MoO nano-heterojunction photocatalyst was synthesized the oxidation sintering method. The properties of the samples were characterized by XRD, SEM, EDX, TEM, UV-vis, PL, FT-IR, BET and electrochemical techniques. The MoS/MoO nano-heterojunction (MS-400) exhibited significantly better photocatalytic activity toward Rhodamine B degradation (0.42634 h) than monomer MoS (∼8.0-folds) and MoO (∼25.6-folds). This is mainly attributed to the MoS/MoO heterojunction interface having an appropriate potential gradient that can promote the interface carrier transportation/separation to optimize the carrier efficiency and increase the solar absorption and specific surface areas/active sites microstructures.
采用氧化烧结法合成了MoS/MoO纳米异质结光催化剂。通过XRD、SEM、EDX、TEM、UV-vis、PL、FT-IR、BET和电化学技术对样品的性能进行了表征。MoS/MoO纳米异质结（MS-400）对罗丹明B降解表现出比单体MoS（约8.0倍）和MoO（约25.6倍）显著更好的光催化活性（0.42634 h）。这主要归因于MoS/MoO异质结界面具有合适的电位梯度，可促进界面载流子传输/分离，以优化载流子效率，并增加太阳能吸收以及微观结构的比表面积/活性位点。
