It was established that modifying additives CeO2, SiO2, and H3PO4 change the catalytic properties of compositions based on ZrO2 in the conversion of ethanol into 1-butanol due to a change in the phase composition of ZrO2, which determines its acid–base properties. As a result of stabilization of the tetragonal ZrO2 phase with additions of CeO2 and H3PO4 an increase in basicity occurs, leading to an increase in the selectivity and productivity of the catalysts in 1-butanol.

改性添加剂对二氧化锆催化乙醇转化1-丁醇性能的影响

已确定改性添加剂 CeO2、SiO2 和 H3PO4 改变了基于 ZrO2 的组合物在乙醇转化为 1-丁醇过程中的催化性能，这是由于 ZrO2 的相组成发生了变化，这决定了其酸碱性能。由于加入 CeO2 和 H3PO4 使四方 ZrO2 相稳定，碱度增加，导致催化剂在 1-丁醇中的选择性和生产率增加。
