Very low temperature CO oxidation over colloidally deposited gold nanoparticles on Mg(OH)2 and MgO

J Am Chem Soc. 2010 Feb 10;132(5):1520-2. doi: 10.1021/ja909351e.

Abstract

The colloidal deposition method was used to prepare Au/Mg(OH)(2) (0.7 wt % gold) catalysts with gold particle sizes between 1.5 to 5 nm which exhibited very high activity for CO oxidation with specific rates higher than 3.7 mol(CO) x h(-1) x g(Au)(-1) even at temperatures as low as -89 degrees C.
