The direct synthesis of hydrogen peroxide is investigated using PdGa/TiO2 and PdIn/TiO2 catalysts prepared by an acid-washed sol-immobilisation procedure, which allows for good control of particle size. The introduction of both Ga and In into a supported Pd catalyst leads to significantly reduced rates of H2O2 degradation in comparison to the monometallic counterpart. Detailed characterisation reveals that this enhancement is a result of selectively tuning the ratio of Pd oxidation states.

使用Pd–Ga和Pd–In催化剂由H2和O2直接合成过氧化氢

使用通过酸洗溶胶固定程序制备的PdGa / TiO 2和PdIn / TiO 2催化剂研究了过氧化氢的直接合成,可以很好地控制粒径。与单金属对应物相比,将Ga和In都引入到负载的Pd催化剂中会导致H 2 O 2的降解速率大大降低。详细的特征表明,这种增强是选择性调节Pd氧化态比率的结果。
