Rh ultrathin two-dimensional nanosheet and preparation method thereof

Abstract

The invention discloses an Rh ultrathin two-dimensional nanosheet which is of a porous structure, wherein the particle size is 50-400nm, and the thickness if 0.4-1nm. The invention also provides a preparation method of the Rh ultrathin two-dimensional nanosheet. The preparation method comprises the following steps of preparing a precursor suspension liquid by taking a rhodium compound as a raw material, then mixing the precursor suspension liquid, a capping agent and a solvent, and performing reaction to obtain the Rh ultrathin two-dimensional nanosheet. The preparation method of the Rh ultrathin two-dimensional nanosheet is simple in process and mild in condition; the obtained nanosheet is of a continuous network-shaped hole structure, is small in thickness, particularly large in specificsurface area, more in exposed active sites, particularly high in utilization ratio of atoms and better in stability and has large potential in catalyzation.

Description

technical field [0001] The invention relates to the technical field of nano catalysts, in particular to a Rh ultrathin two-dimensional nano sheet and a preparation method thereof. Background technique [0002] The original idea of ​​"nanoscience" came from a lecture given by the famous physicist Feynman at Caltech University in 1959, and it has emerged since the 1990s. Nanoscience is considered to be a hot subject that has a very important impact on the emergence and development of a series of high-tech in the 21st century. It is listed as one of the key technologies in the 21st century by countries all over the world, and a lot of manpower and material resources are invested in research and development. [0003] Ultrathin two-dimensional nanomaterials are an emerging class of nanomaterials, which have a sheet-like structure with a horizontal dimension of more than 100 nm or a few microns or even larger, but a thickness of only one or a few atoms (typically less than 5 nm). ...
