Reduced graphene oxide supported molybdenum oxide @ silver phosphate (RGO‐MoO₃@Ag₃PO₄) ternary hybrid composite was prepared by simple mixing of RGO supported MoO₃ nanorods into Ag₃PO₄ nanosphere. Upon visible light exposure, the photocatalytic degradation of MB revealed that the 30 wt.% RGO‐MoO₃@Ag₃PO₄ photocatalyst led to 2.9 times higher activities than pure Ag₃PO₄, 6.2 and 8.7 times compared to RGO‐MoO₃ and pure MoO₃, respectively. Degradation of MB using 30 wt.% RGO‐MoO₃@Ag₃PO₄ is 2.9 and 15 times higher compared to RhB and MO respectively. The downward band bending of Ag₃PO₄ at the interface of RGO‐MoO₃@Ag₃PO₄ was investigated based on the electric field formed. The formed electric field at the interface of RGO‐MoO₃@Ag₃PO₄ is found to be 50 mV which avoids the recombination rate of electron‐hole pairs at the interfaces. This formed electric field promotes the higher separation efficiency of electrons‐holes pairs and longer life time of photoexcited electrons in the RGO‐MoO₃@Ag₃PO₄ resulting higher efficiency and stability. RGO act as an electron acceptor and transporter during charge transfer process between MoO₃ and Ag₃PO₄.

还原石墨烯-氧化物-负载的氧化钼@磷酸银三元杂化复合材料的界面电场研究：高效可见光驱动的光催化剂

还原氧化石墨烯负载的氧化钼@磷酸银（RGO-MoO ₃ @Ag ₃ PO ₄）三元杂化复合材料是通过将RGO负载的MoO ₃纳米棒简单混合到Ag ₃ PO ₄纳米球中制备的。在可见光下，MB的光催化降解表明，RGO‐MoO ₃ @Ag ₃ PO ₄光催化剂的活性比纯Ag ₃ PO ₄高2.9倍，比RGO‐MoO _3高6.2倍和8.7倍和纯MoO ₃。使用30 wt。％RGO-MoO ₃ @Ag降解MB₃ PO ₄分别比RhB和MO高2.9倍和15倍。基于形成的电场，研究了RGO-MoO ₃ @Ag ₃ PO ₄界面处Ag ₃ PO ₄的向下带弯曲。在RGO-MoO ₃ @Ag ₃ PO ₄的界面处形成的电场为50 mV，这避免了界面处电子-空穴对的复合率。形成的电场促进了RGO-MoO ₃ @Ag ₃ PO ₄中电子-空穴对的更高分离效率和更长的光激发电子寿命。从而带来更高的效率和稳定性。在MoO ₃和Ag ₃ PO ₄之间的电荷转移过程中，RGO充当电子受体和转运体。
