Preparation method of magnetic nano-enzyme for removing H2O2 in semiconductor process wastewater

The invention provides a preparation method of a magnetic nano-enzyme for removing H2O2 in semiconductor process wastewater, and belongs to the technical field of water treatment catalyst preparation. According to the method, a metal organic framework material (MOFs) with a porphyrin-like active structure is adopted as a precursor, deprotonation of an imidazolyl ligand in a system is regulated and controlled through triethylamine alcoholysis by utilizing the double-exchange characteristic of metal and the ligand of the metal organic framework material, and therefore the iron and zinc co-doped MOFs material is prepared. And carrying out mesoporous silicon protection, high-temperature pyrolysis, template removal and other treatment operations on the precursor to prepare the iron-based nano-enzyme carbon material. The problems that high-concentration H2O2 in semiconductor wastewater damages equipment and the wastewater treatment efficiency is reduced are solved, and the iron-based nano-enzyme carbon material pre
