Zusammenfassung:The invention discloses a catalyst used in preparation of fluorine-containing low carbon alcohol and a preparation method for the catalyst. The catalyst is characterized by consisting of active ingredients A and B, wherein A is one of Cr and Fe, and B is one of Cu, Zn and Ni; the molar ratio of A to B is 1: (1-10); the catalyst is prepared by adopting a co-precipitation method, and mixed hydroxides are generated by the co-precipitation method and roasted to form a catalyst precursor; and the precursor is reduced through hydrogen and subjected to hydrogen fluoride (HF) pretreatment to form the catalyst. The method used in preparation of the fluorine-containing low carbon alcohol is high in catalytic efficiency and high in raw material conversion rate and product selectivity.
