【摘要】 采用H2O2和HClO4对竹炭进行改性,并用氧化负载法(以H2O2和NaClO为氧化剂)改进金属钯在载体竹炭上的负载,制备出钯/竹炭催化剂(Pd/BC)。经对湿地松松香的歧化反应试验,并与市售钯/炭(Pd/C)催化剂比较,结果表明,以H2O2和HClO4体积比1∶1混合溶液改性竹炭,并以H2O2和NaClO体积比5∶1混合氧化剂负载钯所得Pd/BC-17催化剂具有较高的催化活性,催化活性优于含钯量5%的市售Pd/C催化剂。更多还原

【Abstract】 The Pd/BC catalyst was prepared through improving the loading process and modifying the bamboo charcoal.The optimal condition is the volume ratio of H2O2 to HClO4 is 1∶1 in modifying process,the volume ratio of H2O2 to NaClO is 5∶1 in oxidation loading process.The activity of Pd/BC catalyst is better than that of commercial product which has palladium content of 5%.更多还原
