摘要: We have developed two strategies to optimize Pd catalysts. On one hand, Ag was introduced into and then they were applied the selective hydrogenation of citral under mild conditions. The addition metallic could tune selectivity made it suitable for conjugated double bond. citronellal increased from 0 (for Pd/C Pd0.7Ag0.3/C) 96 % Pd0.4Ag0.6/C) as content increased. other SnO2 catalysts more inclined activate C=O bond gave better performance compared with corresponding Pd–Ag 76 % Pd0.7Ag0.3–SnO2/C used) after SnO2. basis these results, we a catalyst (Pd0.6Ag0.4–SnO2/C) best catalytic (the conversion reached 99 %, up 96 %).
