Application of Pillared Clays for Water Recovery

Catalysts, Journal Year: 2025, Volume and Issue: 15(2), P. 159 - 159

Published: Feb. 9, 2025

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.

State of Art and Perspectives in Catalytic Ozonation for Removal of Organic Pollutants in Water: Influence of Process and Operational Parameters

Catalysts, Journal Year: 2023, Volume and Issue: 13(2), P. 324 - 324

Published: Feb. 1, 2023

The number of organic pollutants detected in water and wastewater is continuously increasing thus causing additional concerns about their impact on public environmental health. Therefore, catalytic processes have gained interest as they can produce radicals able to degrade recalcitrant micropollutants. Specifically, ozonation has received considerable attention due its ability achieve advanced treatment performances at reduced ozone doses. This study surveys summarizes the application treatment, paying both homogeneous heterogeneous catalysts. review integrates bibliometric analysis using VOS viewer with systematic paper reviews, obtain detailed summary tables where process operational parameters relevant are reported. New insights emerging from homogenous applied for removal emerged discussed this paper. Finally, activities a variety catalysts been assessed chemical–physical such point zero charge (PZC), pKa, pH, which determine effect (positive or negative) processes.
