Study on the Surface Location of Reactive Metals of Rh-Mn/SiO2 Catalyst in Ethanol Synthesis from Syngas
In this paper,in-situ EPR,TPSR and NMR were used to study the Rh-Mn/SiO2 catalyst for ethanol synthesis.The results show that the reactive metals Rh and Mn are fixed on the catalyst surface by the interaction with Si-OH,which can enhance the stability of highly dispersed metals.Rh and Mn interact with each other to form the acitve site with high ethanol synthesis activity.The surface Si-OH was found to be of significance on the preparation of catalyst with high catalytic activity.
