Catalytic Wet Air Oxidation (CWAO) has recently been recognized as a promising technique for degrading persistent organic pollutants, such phenol, in wastewater. Among various catalysts, Pillared Interlayer Clays (PILCs) stand out due to their high specific surface area and porous nature. This review delves into the latest progress CWAO processes utilizing PILCs degradation of contaminants phenol It meticulously assesses synthesis PILCs, structural properties, including monolithic forms, understand effect on catalyst efficiency. Key insights how these attributes affect rate process's stability are discussed, providing crucial direction enhancing performance. The highlights significance choosing catalysts that offer balance between cost-efficiency operational efficacy under mild conditions. recent results reported, summarized, compared, thus proving feasibility using materials removal. reaction parameters, conversion, mechanisms highlighted. catalytic efficiency was significantly affected by methods outperformed most costly catalysts. highlighted especially advantageous offering strong performance at lower costs, which boosts up-scaling opportunities methods. analysis also points research gaps proposes directions future studies, exploring innovative PILC improve effectiveness durability further. stresses need incorporate environmental sustainability considerations design selection, aligning with principles green chemistry wastewater treatment. Finally, we conclude proposing new further naturally-based modifications, is approach perform more efficiently.

In this work, catalytic activity of natural chalcopyrite (CuFeS2) was improved by thermal activation. The modified used as efficient catalyst for degradation organic dye Rhodamine B (RhB) through advanced oxidation process (AOP). Effects dosage, H2O2 concentration, reaction temperature, solution pH, anions, and matter on the efficiency RhB were investigated. This study revealed that activation at 300°C changed chemical valency surface elements rather than transforming major phase chalcopyrite. Fenton-like significantly thermally activated could be obtained under broad pH showed high resistance to anions. Under optimal conditions 43.0 mM, 0.75 g/L, initial 4.0, temperature 25°C, reached 96.7% 50 min. Based rate constant kinetics, energy calculated 9 kJ/mol. Radical scavenging experiments electron paramagnetic resonance (EPR) technique demonstrated dominated generated hydroxyl radicals in chalcopyrite/H2O2 system. formation sulfates resulted from induced dissolved copper or iron ions, promoted facilitated reactive radicals. work provides an in-depth understanding mechanism behind enhance chalcopyrite, offering a theoretical basis utilizing minerals treatment wastewater towards cleaner production.
