WebIt is a way to identify optically active compounds. This is actually a very important topic in biochemistry. Many systems in the body perform functions with optically active compounds. Only if the compounds are oriented in a certain fashion can the biochemical processes take place. ( 3 votes) 😊 6 years ago WebPhotocatalysts cause the generation of reactive oxygen, which helps in the decomposition of contaminants. Incorporating two photocatalysts with various bandgaps leads to a greater separation of electron/hole pairs, where more species would exist for reactions to degrade contaminants.
