| titleOfInvention | A kind of coal gangue-based catalytic material and its preparation method and application |
| abstract | The invention provides a coal gangue-based catalytic material and its preparation method and application, which belong to the field of solid waste recycling and environmental pollution control. The present invention uses coal gangue as raw material, realizes mechanical dissociation and activation of coal gangue through grinding, increases active sites and active groups on the surface of coal gangue; adds metal chlorides, uses kaolinite in coal gangue as a skeleton, and realizes The ore phase of metal ions is fixed to form a stable mineral phase, which can avoid secondary pollution caused by metal ion leaching in the subsequent application process; through roasting, the in-situ carbon activation of coal gangue is realized, and the formation of a new pore structure of roasted coal gangue is promoted. , the specific surface area of the material is improved, and the increase of defect sites and active sites of coal gangue is realized; the preparation process is simple and the cost is low. The results of the examples show that when the catalytic material prepared by the present invention catalyzes persulfate, it has a good degradation effect on various common organic substances in soil. |
