。采用改进的浸渍法制备了Au-Pd / TiO 2催化剂，研究了由h2分子和o2直接合成过氧化氢（h2o2）的方法。最初，我们研究了Au: Pd比例对h2o2形成的催化活性的作用，以及在先前发现的使用高压反应物和低温形成h2o2的最佳条件下其随后的降解。随后，我们对环境条件下的h2o2合成进行了详细的研究，环境条件对实现高产量的h2o2更具挑战性，并且更有可能用于未来的工业应用。
. The direct synthesis of hydrogen peroxide (H 2 O 2 ) from molecular H 2 and O 2 over Au-Pd / TiO 2 catalysts prepared using a modified impregnation methodology is studied. Initially we investigated the role of Au: Pd ratio on the catalytic activity towards H 2 O 2 formation and its subsequent degradation under conditions that have previously been found to be optimal for the formation of H 2 O 2 using high pressure reactants and low temperatures. Subsequently, we have conducted a detailed study of H 2 O 2 synthesis under ambient conditions which are both more challenging for achieving high yields of H 2 O 2 and are more likely to be used for future industrial applications.
