Catalyst Group
- What is Catalysis?Catalysis is like having a shortcut in a long journey—it helps chemical reactions happen faster and with less activation energy. Our own bodies use catalysts, called enzymes: the enzyme amylase in your saliva helps break down starch (like bread or rice) into sugar—much faster than if it happened on its own!
- Why Environmental Catalysis?Like in our body, the environment has a lot of processes with high activation energy. Our team works to develop catalytic systems to break down harmful pollutants in air, water, and soil, making our world cleaner and safer.
An example of environmental catalysis is catalytic converters in our cars that convert toxic gases into not harmful ones!Read more

Catalysts used in WTP/WWTP
Common catalytic processes include ozonation, photocatalysis, Fenton-like reactions, and catalytic filtration, using materials like metal oxides, MOFs, carbon-based media, and zeolites to improve treatment efficiency and reduce chemical consumption.
- Metal and metal oxidesThese catalysts, including iron, copper, and manganese oxides, are known for their strong redox properties and stability. They are widely used for contaminant breakdown, disinfection, and nutrient removal in filtration, chemical oxidation, and membrane systems.
- Metal–Organic FrameworksMOFs are porous crystalline materials made from metal ions and organic linkers, offering high tunability and surface area. They are emerging materials for selective adsorption, contaminant sensing, and removal of pharmaceuticals, dyes, and metals.
- Carbon-based CatalystsCarbon materials like activated carbon, biochar, and graphene are valued for their large surface area and strong adsorption abilities. They are applied in pollutant removal, filtration systems, and as supports for hybrid catalysts in various water treatment technologies.
- Zeolites and claysZeolites and clays are porous aluminosilicates with high ion-exchange capacity and strong adsorption properties. They are commonly used to remove heavy metals, ammonium, and organic pollutants through adsorption and immobilization.
