Photocatalyst
A photocatalyst is a light-activated material that breaks down bacteria and harmful pollutants in water through a chemical reaction, without being consumed. Xatoms has developed 8 patent-pending photocatalysts that harness visible light—unlike traditional UV-based methods—to break down contaminants in water, offering a scalable, affordable, and energy-efficient purification solution.

Advanced Oxidation Leveraging Sunlight
Xatoms' photocatalysts are activated by sunlight or visible LED light to trigger a chemical process called oxidative decomposition. When light hits the photocatalytic material, it energizes electrons that generate reactive oxygen species (like hydroxyl radicals ·OH and superoxide ions O₂⁻). These highly reactive molecules then attack and break down contaminants such as bacteria, viruses, harmful chemicals, and odors.
