摘要：

The stability of Cu/SiO2 catalysts was studied at 353 K in aqueous phase in the presence of hydrogen. Complex phenomena appeared : partial oxidation of the metallic surface, partial dissolution of oxidized copper species and readsorption of copper ions. From these observations a mechanism is suggested for the metal sintering, via solvated ionic species.
