摘要：

Stereoselective hydrogenation of alpha-pinene over heterogenous catalysts under solvent-free conditions is promising for biomass conversion but challenging. Herein, we prepared the Ru-NiO/H beta catalysts using chemical reduction and galvanic replacement methods. With the increase of Ni content, the selectivity of cis-pinane was significantly improved. A high conversion of 100 % and a high cis-pinane selectivity of 98 % were achieved after 4 h reaction at 80 degrees C. It has been verified that the addition of Ni can adjust the ratio of Bronsted and Lewis acid, regulate the hydrogen spillover between Ru and support, change the adsorption site of substrate and form steric hindrance effect. All these contribute to the better selectivity of the catalyst. In addition, catalysts presented good stability in the 900 h test.
