description | The invention provides a hydrophobic transition metal composite catalyst as well as a preparation method and application thereof, and belongs to the technical field of collaborative removal of VOCs and NOx pollutants in flue gas. The preparation method comprises the following steps: mixing a metal active component, fatty alcohol-polyoxyethylene ether, ethylene glycol and an alcohol solvent to obtain a precursor solution; mixing starch, melamine, cyclodextrin, glucose and ammonia water to obtain a ligand solution; mixing the precursor solution and the ligand solution, then carrying out hydrothermal treatment, carrying out preheating treatment on the obtained catalyst precursor in a protective atmosphere, and then roasting in a carbon dioxide atmosphere to obtain the catalyst precursor; mixing the catalyst precursor, a titanium dioxide precursor and an adhesive, and drying to obtain a catalyst ligand; and carrying out shaping treatment on the catalyst ligand in a protective atmosphere to obtain the hydrophobic |
