A kind of preparation method and application of composite heterojunction photocatalyst |
| abstract |
A preparation method and application of a composite heterojunction photocatalyst belong to the fields of resource utilization and environmental purification. 70-95 parts of high-speed iron red mud and 5-30 parts of biomass-based reducing agent, the high-speed iron red mud and the reducing agent are mixed uniformly and molded under a pressure of 0.5-3MPa; the obtained mixture is calcined at a temperature of 200-400° C.; finally The photocatalyst is obtained by taking out the mixture and grinding it through a sieve. The method adopts biomass pyrolysis to convert the Fe 2 O 3 part of the high iron red mud into magnetic Fe 3 O 4 , so that the catalyst has magnetic properties and is convenient for recycling; The combination of Fe 2 O 3 and TiO 2 makes Fe 2 O 3 and TiO 2 form a heterojunction; the pyrolysis product carbon is combined with the catalyst particles, which improves the adsorption and electrical conductivity of the catalyst; it is beneficial to improve the degradation efficiency of the catalyst; The low-molecular-weight pollutants that are not completely degraded are adsorbed to the surface of the catalyst for re-degradation to prevent secondary pollution. The entire degradation process is simple to operate and effectively achieves the purpose of self-cleaning. The raw materials used are readily available and economically feasible. |
