Abstract

Temperature-programmed reductive decomposition, temperature-programmed reduction, and catalytic hydrogenolysis reactions show that PtRe x bimetallic particles are selectively formed during reductive decomposition of Re 2(CO) 10 on pre-reduced Pt/NaY. After deposition, heating in a reducing atmosphere causes initial carbon monoxide removal by hydrogen displacement, subsequently, coalescence of zerovalent clusters occurs, while complete removal of carbon monoxide takes place by the formation of methane and water.
