Abstract

A series of Rh-based catalysts with various crystalline phases (p25, anatase, and rutile) were prepared the incipient-wetness impregnation method. It was found that these catalysts had different metal-support interactions. Hence, 1%Rh/p, 1%Rh/r, and 1%Rh/a exhibited methane, CO, and methanol selectivity, respectively.

摘要

通过初湿浸渍法制备了一系列具有不同晶相（p25、锐钛矿和金红石）的铑基催化剂。发现这些催化剂具有不同的金属-载体相互作用。因此，1%Rh/p、1%Rh/r和1%Rh/a分别表现出对甲烷、一氧化碳和甲醇的选择性。
