γ-Al₂O₃ and silica-doped aluminas are largely used supports for industrial catalysts. The addition of silica to alumina modifies its acid–base properties, also affecting its dispersion ability of supported species. In this paper, investigations on the silica doping effect in alumina-supported MoO₃ catalysts, developed for the oxidative dehydrogenation process of ethanol to acetaldehyde, are reported.

钼催化剂在乙醇氧化中的研究。第 2 部分。氧化铝负载和二氧化硅掺杂的氧化铝负载的 MoO3

γ-Al ₂ O ₃和二氧化硅掺杂的氧化铝主要用作工业催化剂的载体。在氧化铝中加入二氧化硅会改变其酸碱性质，也影响其对负载物的分散能力。在本文中，报告了对氧化铝负载的 MoO ₃催化剂中二氧化硅掺杂效应的研究，该催化剂是为乙醇氧化脱氢制乙醛过程开发的。
