Abstract

In this communication, we report novel Ru/NiAl-layered double hydroxide derived catalysts for CO removal by selective CO methanation. The experimental results revealed that uncalcined Ru/NiAl catalyst shows the fine dispersion of the nickel particles and remarkably high activity to CO at wider operating temperature window ranging from 150°C to 250°C. This work shows promising potential in further application of selective CO methanation as deep CO removal process of fuel processors especially for polymer electrolyte membrane fuel cells (PEMFC).
