Highly Active Mixed-Phase Cu–Al Catalyst for Methanol Steam Reforming

Abstract

In the present study, mixed-phase Cu–Al catalysts have been synthesized by an autocombustion method using glycine as fuel. By adjusting the ratio of glycine, the self-reductive Cu–Al mixed oxides were prepared and demonstrated higher activity than a commercial Cu-based catalyst in the catalytic performance test, where the WHSV was 12/h and the steam/methanol ratio was 1.1. The relationships between the physicochemical properties of the prepared Cu–Al catalysts and the catalytic performance have thoroughly been investigated by various characterization methods, such as BET, in-situ XRD and TEM.
