| Abstract: | Selective hydrogenation of o-xylene on silica supported noble metals Pd, Rh, Ni, Pt, Ir, Ru, Os and Re has been studied. A correlation between the heat capacity of the metal conduction electrons and the selectivity towards the cis-product was found. Thermal effect in activity and selectivity is reported.
