Preparation Of Rh-PPy-RGO Ternary Hybrid Materials By Redox Reaction And Study On Catalytic Properties

As one of the most important the noble metal catalysts, Rh-PPy-RGO hybrid nanomaterials and different kinds of morphologies platinum nanomaterials have drawn attention widely because of their highly enhanced catalytic performance and wide range of applications. The noble metal catalysts are often required to work at relatively high temperatures to meet practical needs. Therefore, in order to obtain higher catalytic activity and more stability of the noble metal catalyst, their hybrid structure be optimized. The hybrid structure mainly was controlled effectively from the angle of the synthesis. The main contents are as follows:1. In order to be able to put the noble metals loaded on the carrier effectively in the paper. A new kind of polymer-polypyrrole can be used as reducing agent and coupling agent.The noble metal was loaded on the surface of graphene by selective precipitation successfully. The noble metal was loaded on the surface of graphene by selective precipitation successfully coupling agent. Rh-PPy-RGO hybrid nanomaterials shows excellent catalytic performance in 4-NP reduce reaction.2. In this paper, the level of highly ordered porous platinum nano helical structure was synthesized by the control the reduction rate of the OTAB-Pt and with the aid of OTAB as a structure directly inducer. Super thin platinum nanowires(less than 2 nm) are the building blocks of the structure which are around a central point. The spiral nano structure has good thermal properties and catalytic properties.
