MOF-derived Fe0/Fe3C@ C/N magnetic mesoporous composite material and preparation method and application thereof

Abstract

The invention discloses an MOF-derived Fe0 / Fe3C@ C / N magnetic mesoporous composite material and a preparation method and application thereof. Firstly, dicarbonyl cyclopentadienyl iron dimer is used as a metal source, benzimidazole-5, 6-dicarboxylic acid is used as an organic ligand, MOF: Fe (Hbidc) is prepared through a hydrothermal method, and then the carbonized derivative Fe<0> / Fe3C@C / N is obtained through high-temperature calcination. The preparation process is simple and controllable, and the preparation period is short. The Fe<0> / Fe3@ C / N nitrogen-doped iron-carbon nano composite material prepared by the method has high PS catalytic activity and strong ferromagnetism, is easy to separate and recover, can be recycled and regenerated, and has a good application prospect in the aspect of persulfate environment catalytic materials.

Description

technical field

[0001] The invention belongs to the technical field of water pollution control, in particular to a magnetic mesoporous composite material Fe derived from a metal organic framework (Metal Organic Framework, MOF) 0 / Fe 3 Synthesis of C@C / N and its method for treating organic wastewater by activating persulfate advanced oxidation system. Background technique

[0002] Water pollution is an increasingly serious global environmental problem, threatening ecosystems and human existence. How to efficiently remove refractory organic pollutants in water and turn sewage into recyclable water resources is very important. Advanced Oxidation Technologies (Advanced Oxidation Technologies) based on persulfate (PS) utilizes strong oxidative free radicals or non-free radical reactive species to degrade pollutants, and has the advantages of high treatment efficiency, rapid response, non-selectivity, and pH adaptation range wide advantages. PS at normal temperature and pressu...
