摘要
以高比表面积椰壳活性炭为载体,柠檬酸钠为还原剂,在100℃条件下对H2PdCl。溶液进行还原负载,制备了直径在3~10rim的Pd/C催化剂。控制柠檬酸钠与HzPdCl。的量,制备了6个不同粒径Pd粒子负载的Pd/C催化剂,制备条件温和。该催化剂能够高效催化Heck反应的进行,反应无需无水无氧条件,无需配体的参与,重复利用次数较多。
Nanoparticle Pd/C catalyst which the palladium partices diameter was 3-10nm was prepared by reducing of H2 PdC14 by sodium citrate and loaded under the high surface area coconut shell activated carbon at 100℃. Six Pd/C cata- lysts were prepared through controlling the dosages of H2 PdCI4 and sodium citrate. The available Pd/C catalyst can catalyze Heck reaction efficiently without dry and anaerobic conditions as well as the absent of ligands, and it can be reused many times.
