The degradation mechanism of catalytic and the pathway of humic acid was revealed. The important parameters such as initial solution concentration, air/pureoxygen, reaction temperature, catalyst dosage, and single-atom loading were discussed. Thestudy of the synergistic enhancement effect of single-atom loading on the catalytic reaction system was emphasized. By using the constructed porous TiZrO4/M hollow sphere catalyst, the catalytic oxidation experiment of humic acidwas carried out, and the degradation mechanism and pathway of humic acid are proposed, revealing the degradation efficiency and the surface catalytic oxidation reaction mechanism of humic acid. Since the prepared H-TiZrO4/M composite catalytic material has unique multi-channel confined structure, the influence of its structure features on the heterogeneous interface adsorption characteristics, the mass transfer capacity and electron transfer rate were studied thoroughly. We published two papers.
