According to the World Health Organization, air pollution causes an estimated 4.2 million deaths annually, highlighting the critical need for effective pollution mitigation strategies.
Photocatalysts offer a promising avenue for breaking down common toxic pollutants by generating charged carriers that can facilitate chemical reactions under light exposure.
Despite their potential, photocatalysts face challenges such as requiring high-energy light to activate and the recombination of charged particles, which can hinder efficiency.
The development of new photocatalysts, using robots and artificial intelligence, aims to enhance the breakdown of pollutants and improve the efficiency of these materials.
