The invention discloses a powder catalyst, which is prepared from GdSnWSbO 9 The particle size of the powder catalytic material is 0.15-0.30 μm; can be used for photocatalytic degradation of organic pollutants in water, such as parachloroaniline, methyl orange and decabromodiphenyl ether. Meanwhile, the preparation method of the powder catalytic material comprises a high-temperature solid-phase sintering method, a direct precipitation method and a chemical vapor condensation deposition method. The invention also discloses a preparation method of the composite nano catalytic material, and GdSnWSbO is prepared 9 The sodium-based montmorillonite composite nano catalytic material can be used for removing organic pollutants in water such as parachloroaniline, methyl orange and decabromodiphenyl ether by photocatalysis. |
