A catalyst prepared by the following methods: 1) preparing zinc-copper bimetallic MOF; 2) dispersing graphite into ethanol, adding nano-titania, ultrasonicating for 15 min, then adding zinc-copper bimetallic MOF, and warming up to 60-80° C., Stir for 3-5 hours, then filter and dry to obtain a mixture; 3) prepare a TiO 2 /graphite catalyst supporting zinc-copper bimetallic MOF. The catalyst of the invention provides energy for the catalysis of the zinc-copper bimetallic MOF by absorbing solar energy through TiO2, so that the zinc-copper bimetallic MOF can effectively catalyze the reaction between CN- and oxygen to generate CO2 and nitrogen, and the graphite has a large specific surface area, which can effectively adsorb Heavy metal ions in wastewater. The raw material of the invention is easy to obtain, the operation is simple and convenient, and it is suitable for industrial promotion and treatment of sewage. |
