WebPhotocatalysis is an advanced oxidation process that has received significant attention due to its low energy requirements and easy operation to break down the organic contaminants into mineral products. Due to the abundance of solar light, semiconductor-based heterogeneous photocatalysis is considered one of the most encouraging technologies … Web5.4.2 Heterogeneous Photocatalysts. Photocatalysts can be assessed based on some specific parameters. The TON of the catalyst quantifies its ability to act upon more than one set of reactant molecules. It is defined as the number of reactants that a catalyst acts upon before it degrades.
