In recent years, efforts have been made in developing new and more efficient water purification methods the synthesis of catalysts with greater catalytic activity that are stable can be used wide pH ranges. Pillared clays represent a viable alternative for removing organic contaminants. The clays, usually smectites, modified by inserting inorganic pillars (Al, Zr, Cr, Fe, Ti, Ga, Mn) between layers clay, increasing its surface area, porosity, activity, thermal stability. This review describes importance using pillared different polyoxycations Fenton, photo-Fenton, ozonation, wet oxidation hydrogen peroxide, photocatalysis processes. iron (Fe-PILCs) promising capable generating hydroxyl radicals oxidize contaminants, thus facilitating their removal. current challenges PILC application at industrial scale also discussed.
