Abstract:		"NO(x), SO(x), and carbonaceous volatile organic compounds (VOCs) are extremely harmful to the environment, and their concentrations must be within the limits prescribed by the region-specific pollution control boards. Thus, NO(x), SO(x), and VOC abatement is essential to safeguard the environment. Considering the importance of NO(x), SO(x), and VOC abatement, the discussion on selective catalytic reduction, oxidation, redox methods, and adsorption using noble metal and non-noble metal-based catalytic approaches were elaborated. This article covers different thermal treatment techniques, category of materials as catalysts, and its structure-property insights along with the advanced oxidation processes and adsorption. The defect engineered catalysts with lattice oxygen vacancies, bi- and tri-metallic noble metal catalysts and non-noble metal catalysts, modified metal organic frameworks, mixed-metal oxide supports, and their mechanisms have been thoroughly reviewed. The main hurdles and potential achievements in developing novel simultaneous NO(x), SO(x), and VOC removal technologies are critically discussed to envisage the future directions. This review highlights the removal of NO(x), SO(x), and VOC through material selection, properties, and mechanisms to further improve the existing abatement methods in an efficient way"
