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