Monolayer nanosheets of Bi2W1–xMoxO6 solid solutions, possessing an average thickness of 0.98 nm, have been rationally designed and constructed by a facile bottom-up route of a hydrothermal reaction. The tiptop photocatalytic efficiency of Bi2W1–xMoxO6 monolayer nanosheets can be achieved for effective reduction conversion of nitrobenzene into anilines under visible light, in conspicuous contrast to the homologous pristine Bi2WO6 and Bi2MoO6 components. The optimal Bi2W0.25Mo0.75O6 monolayer nanosheets exhibit a high selectivity and stability for photocatalytic nitrobenzene reduction, affording a high aniline generating rate of 650 μmol g–1.h–1, in excess of the previously reported ordinary photocatalysts. The good photocatalytic property could be due to the lattice distortion in solid solutions for structural polarity by the more electronegative W substitution, leading to the efficient interfacial and interior separation of photogenerated carriers. The structure–activity relationship of Bi2W1–xMoxO6 demonstrates a novel insight to devise property-controllable photocatalysts at the atomic level with high efficiency for organic photocatalytic reactions.

单层Bi 2 W 1– x Mo x O 6固溶体，用于结构极性，可在可见光下促进硝基苯的光催化还原
Bi 2 W 1– x Mo x O 6固溶体的单层纳米片平均厚度为0.98 nm，已经通过水热反应的简单的自下而上的途径进行了合理设计和构建。与同源的原始Bi 2 WO 6和Bi 2 MoO 6组分形成鲜明对比，可以实现Bi 2 W 1– x Mo x O 6单层纳米片的尖端光催化效率，以将硝基苯在可见光下有效还原转化为苯胺。最佳Bi 2 W0.25 Mo 0.75 O 6单层纳米片对光催化还原硝基苯具有很高的选择性和稳定性，苯胺的生成速率高达650μmolg –1。h –1，超过以前报道的普通光催化剂。良好的光催化性能可能是由于固溶体中的结构极性被更多的负电性W取代所致，从而导致了光生载流子的有效界面和内部分离。Bi 2 W 1– x Mo x O 6的构效关系 展示了一种新颖的见解，可设计出原子级的性质可控的光催化剂，以高效地进行有机光催化反应。
