A series of Co-Ce clay-based catalysts were prepared via the wet impregnation method and tested for catalytic combustion diesel soot carbon monoxide. The objective this work was to find a suitable catalyst with an optimized active phase composition in order structure system using 3D-printing technique. physicochemical characterization indicated that support mainly composed kaolinite quartz. When supported on commercial clay, mixture oxides (Co3O4 spinel CeO2 fluorite) had higher activity than individual oxides. formation solid solution verified along synergistic effect between these two selected metal optimal molar Co:Ce = 90:10. corresponding showed highest combustion, 335 °C being temperature maximum rate. Also, it produced best CO oxidation. This formulation balanced proportion Co3+ Co2+ surface content Ce3+ species among prepared, which played key role oxidation reactions studied.

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.
