The photothermal-catalyzed CO reduction is severely limited by the low carrier transport capacity. In this paper, the in-situ construction of 0D/2D BiMoO (BMO)/reduced Graphene Oxide (rGO) heterojunction was synthesized. The excellent photothermal conversion ability of rGO promotes the high dispersion of BMO quantum dots (QDs). The size of synthesized BMO QDs is about 4.26 nm and the temperature of the catalysts can quickly rise to 68.0 °C. XPS results show that the C–O–Bi interfacial electronic bridge between surface oxygen-containing groups and BMO QDs was successfully induced by modulating the degree of GO reduction. Electrons generated by BMO QDs migrate to the rGO surface rapidly, inducing rGO as a new electron-rich surface for rapid activation of CO. The 1:5 BMO/rGO (NaBH) CO yield reaches 186.87 μmol/g, which is 4.64 times as much as BMO QDs.

0D/2D Bi2MoO6 量子点/rGO异质结促进全太阳光谱驱动的光热催化二氧化碳还原为太阳能燃料

光热催化CO还原受到低载流子传输能力的严重限制。本文合成了原位构建的 0D/2D BiMoO (BMO)/还原氧化石墨烯 (rGO) 异质结。 rGO优异的光热转换能力促进了BMO量子点（QD）的高分散性。合成的BMO量子点尺寸约为4.26 nm，催化剂温度可快速升至68.0 °C。 XPS结果表明，通过调节GO还原程度成功诱导了表面含氧基团和BMO量子点之间的C-O-Bi界面电子桥。 BMO QDs产生的电子快速迁移到rGO表面，诱导rGO成为新的富电子表面，用于快速激活CO。1:5 BMO/rGO (NaBH) CO产率达到186.87 μmol/g，是rGO的4.64倍。就像 BMO QD 一样。
