ResumoPd and Pd–Sn supported on SiO2 and active carbon were prepared and tested as catalysts in the hydrogenation of maleic anhydride. Particularly Pd–Sn/SiO2 was active and selective in the hydrogenation of maleic anhydride to γ-butyrolactone, and showed a resistance to the deactivation. The results of XPS and CO adsorption evidenced that the catalytic performance of Pd–Sn/SiO2 was related to the modification of electronic configuration of Pd due to the effective interaction between Pd and Sn.
