实验室制备负载型催化剂，用gamma Al2O3作为载体，负载活性组分后，洗涤过滤时，抽滤特别慢，怎么办啊？ 高人指点 先调PH值试试吧
Cu/ZrO2/S2O8(2-)/gamma-Al2O3 solid acid catalyst was prepared by loading of (NH4)2S2O8, ZrOCl2, and Cu(NO3)2 onto gamma-Al2O3 step by step, which was obtained from calcining of pseudoboehmite. The catalytic property of Cu/ZrO2/S2O8(2-)/gamma-Al2O3 on the
