The invention discloses MgAl-LDH/N- (BiO) 2 CO 3 The preparation method of the composite material comprises the following steps: firstly, after the bismuth ammonium citrate is hydrothermally treated, the magnesium nitrate, the aluminum nitrate and the sodium hydroxide are added to obtain the bismuth ammonium citrateTo MgAl-LDH/N- (BiO) 2 CO 3 A composite material. The method has the advantages of low cost, simple operation, high efficiency and energy conservation, and the obtained composite material is applied to photocatalytic degradation of pollutants in dye sewage. |
