Heterostructured RGO/Bi_3.64Mo_0.36O_6.55 nanospheres with different weight fractions of RGO were synthesized via a simple and practical low-temperature solution-phase route by using Bi_3.64Mo_0.36O_6.55 nanospheres as substrate materials. The as-prepared RGO/Bi_3.64Mo_0.36O_6.55 nanoheterostructure included RGO nanoparticles assembling on the surface of Bi_3.64Mo_0.36O_6.55 nanospheres. Comparing with pure Bi_3.64Mo_0.36O_6.55, RGO/Bi_3.64Mo_0.36O_6.55 hybrid photocatalysts exhibited enhanced photocatalytic activities under visible light irradiation in the decomposition of rhodamine B (RhB) solution, and the RGO/Bi_3.64Mo_0.36O_6.55 photocatalyst with 3 wt% of RGO exhibited the highest photocatalytic activity. The enhanced performance is believed to be induced by the high specific surface area, the strong visible-light absorption originating from the sensitization of RGO, and the high efficient separation of photogenerated electron–hole pairs through RGO/Bi_3.64Mo_0.36O_6.55 heterostructure.

异质结构的RGO / Bi _3.64 Mo _0.36 O _6.55纳米球：合成和增强的可见光驱动的光催化活性

以Bi _3.64 Mo _0.36 O _6.55纳米球为基底材料，通过简单实用的低温固溶相合成了具有不同RGO重量分数的异质结构RGO / Bi _3.64 Mo _0.36 O _6.55纳米球。所制备的RGO / Bi _3.64 Mo _0.36 O _6.55纳米异质结构包括在Bi _3.64 Mo _0.36 O _6.55纳米球表面上组装的RGO纳米颗粒。与纯Bi _3.64 Mo _0.36 O _6.55相比，RGO / Bi _3.64 Mo在罗丹明B（RhB）溶液的分解中，_0.36 O _6.55杂化光催化剂在可见光照射下表现出增强的光催化活性，具有3 wt％RGO的RGO / Bi _3.64 Mo _0.36 O _6.55光催化剂表现出最高的光催化活性。据信，增强的性能归因于高比表面积，源自RGO敏化的强烈可见光吸收以及通过RGO / Bi _3.64 Mo _0.36 O _6.55异质结构对光生电子-空穴对的高效分离。
