Au-Pt/Co_3O_4 catalyst for methane combustion

摘要

The catalytic activity of Au/Co_3O_4 (Au loading was 2-5 wt.%) towards methane combustion could be enhanced when small amount of Pt,e.g.0.2wt.% was added,and the temperature for 100% conversion of methane could be decreased by catalytic activity than Au-Pt/Co_3O_4 when combined with Au over the Co_3O_4 support.
