  ABSTRACT: Volatile Organic Compounds (VOCs) are harmful air pollutants requiring efficient treatment technologies. Catalytic oxidation using Platinum Group Metal (PGM) catalysts is highly effective but hindered by their high cost. This review explores advanced strategies for fabricating low-loading PGM catalysts to achieve cost-effective VOC purification. The review focuses on synthesis methods such as strong electrostatic adsorption, colloidal synthesis, and single-atom catalyst preparation that maximize atomic efficiency by enhancing metal dispersion and strengthening metal-support interactions. The role of innovative supports, including redox-active oxides, zeolites, and carbon-based materials, in stabilizing low PGM loadings and promoting activity is also discussed. The application of these catalysts in oxidizing VOCs like toluene, formaldehyde, and chlorinated compounds is critically examined, demonstrating that rational design can yield superior performance with minimal metal use, paving the way for sustainable air pollution control.
