摘　　要：Pd/BN催化剂可以有效催化顺酐加氢制备丁二酸酐反应,催化剂的预还原温度显著影响其催化性能。除了移除残氯和影响Pd粒子长大,本文证实了还原温度同时极大地影响Pd粒子的落位,落位于配位不饱和的BN片层边缘的Pd粒子催化活性更高。Pd/BN catalysts can effectively catalyze the hydrogenation of maleic anhydride to succinic anhydride,and the prereduction temperature of the catalyst significantly affects its catalytic performance.In addition to removing residual chlorine and affecting the growth of Pd particles,it has been confirmed that the reduction temperature also greatly affects the location of Pd particles,and Pd particles located at the coordinatively unsaturated edge sites of BN layers show higher catalytic activity.

关 键 词：Pd/BN催化剂 顺酐加氢 还原温度
