SUPPORTED NANO AG/MNCEO X/ATTAPULGITE CATALYST AND PREPARATION METHOD THEREFOR

WIPO Patent Application WO/2020/220193

A1

The present invention provides a supported nano Ag/MnCeO x/attapulgite catalyst and a preparation method therefor. The preparation method comprises: (1) preparing acidified attapulgite; (2) preparing a molded supported nano MnCeO x/attapulgite catalyst; and (3) preparing a molded supported nano Ag/MnCeO x/attapulgite catalyst. In the molded supported nano Ag/MnCeO x/attapulgite catalyst, the load of MnCeO x mixed oxide is 10-20%, and the load of nano Ag is 0.4-2.0%. In the MnCeO x mixed oxide, the molar ratio of Mn to Ce is 4-1:1. The molded supported nano Ag/MnCeO x/attapulgite catalyst prepared by the present invention solves the problem that powder is difficult to be used in industry.
