提出一种新的复合固体超强酸催化剂WO_3-ZrO_2-SO_4~(2-)及其合成方法.用指示剂法测定其700～800℃范围内烧制样品的酸强度H_o≤-16.04;吸附吡啶的红外光谱表明,其表面同时存在B酸中心和L酸中心。
A new composite solid superacid catalyst WO_3-ZrO_2-SO_4 ~ (2-) and its synthesis method were proposed and the acidity of the samples sintered at 700 ~ 800 ℃ was determined by the indicator method H_o≤-16.04. The adsorption of pyridine The infrared spectrum shows that there are both B acid center and L acid center on the surface.
