摘要
分别采用H2和KBH4对Pd γ-Al2O3催化剂进行还原,并进一步考察了它们在蒽醌加氢制备双氧水反应中的催化活性。试验结果表明,用KBH4还原的催化剂具有较高的活性和较长的使用寿命,并对此进行了表面分析。
Two Pd/γ-Al_2O_3 catalysts were reduced by H_2 and KBH_4 respectively and their catalytic activities in anthraquinone hydrogenation to produce H_2O_2 were introduced.Results indicated the catalyst reduced by KBH_4 showed higher activity and longer service life than that reduced by H_2. Surface analysis of the two catalysts was carried out.
