| 摘 要： | 以介孔分子筛 MCM-41作为催化剂的载体，采用微波辅助方法一步合成2种不同 n(Pd)/n(Si)的负载型催化剂 Pd-MCM-41，采用 XRD、FT-IR及 N2吸附-脱附对 Pd-MCM-41进行表征，并将其应用于催化低浓度甲酸分解反应，考察在常规加热和微波加热条件下，Pd 负载量、反应温度和反应时间对甲酸在 Pd-MCM-41上分解反应的影响。结果表明，微波辅助成功地合成了Pd-MCM-41催化剂，其对低浓度甲酸分解反应有一定的催化效果；提高反应温度和延长反应时间，均有利于低浓度甲酸分解；与常规加热条件相比，在微波加热条件下Pd-MCM-41对甲酸分解反应的催化效果更好。
