Red phosphorus with three-dimensional nanostructure (3D-RP) was prepared by a hydrothermal method using commercial micron-sized RP as precursor. The investigation indicates that 3D-RP can harvest most of the visible light (Eg = 1.79 eV) and the BET surface area can reach 54.3 m2/g. It is interesting that 3D-RP exhibits quick adsorption property for methylene blue (MB) during the static adsorption experiment. Besides, Au and Cu ions can be adsorbed and reduced to their metallic states over the surface of 3D-RP without adding any reducing agent. Au and Cu species can greatly improve the photocurrent intensity and the photocatalytic hydrogen production efficiency of 3D-RP. This work is the primary investigation on the element phosphorus photocatalyst, further work should be conducted to explore more interesting properties about nano-sized RP.

三维红磷:具有优异的吸附和还原性能的有前途的光催化剂

采用商业微米级RP作为前驱体,通过水热法制备了具有三维纳米结构的红磷(3D-RP)。研究表明3D-RP可以收集大部分可见光(Eg = 1.79 eV),并且BET表面积可以达到54.3 m 2/G。有趣的是,在静态吸附实验过程中3D-RP表现出对亚甲基蓝(MB)的快速吸附性能。此外,可以在3D-RP的表面上吸附Au和Cu离子并将其还原成金属态,而无需添加任何还原剂。金和铜物质可以大大提高3D-RP的光电流强度和光催化制氢效率。这项工作是对元素磷光催化剂的初步研究,应该进行进一步的工作以探索有关纳米级RP的更有趣的性质。
