摘　　要：以对苯二胺为配体合成非均相钯纳米粒子催化剂(Pd-NPs),该钯催化剂的合成步骤简单,常温、常压下,氢气作为氢源,以水作为溶剂即可还原各种芳香族肟、酮和醛生成相应胺和醇,多数产物都有优秀的产率,部分高达99%,此外,该催化剂具有良好的可持续利用工业应用前景.In this paper,we use p-phenylenediamine as ligands to simply synthesize a palladium-based heterogeneous catalyst with high performance.Notably,the stable Pd-NPs can effectively catalyze the reduction reaction of aromatic oximes,ketones and aldehydes with H 2 in aqueous solution at atmospheric pressure and room temperature.Besides,some amines and alcohols can achieve superior yields up to 99%.Furthermore,the Pd-NPs catalyst also has great potential for sustainable industrial applications.
