Abstract: The dimerization of conjugated cyclic olefins during hydrogenation at low temperatures (≤250 °C) on a spent commercial Ni–Mo–S/γ-Al2O3 catalyst is reported. Hydrogenation of 4-methylstyrene versus α-methylstyrene showed that the methyl group attached to the vinyl… read more here.

Abstract: The durability of supported metal catalysts usually suffers from sintering, the metal nanoparticles aggregating into larger sizes and subsequent loss of reactive surface, resulting in catalysts deactivation when heated at elevated temperatures. Herein, we investigate… read more here.
