Abstract Water is the main source of sustaining life. It is an indispensable need for
flora and fauna alike. However, water is often contaminated by multidrug-resistant
bacteria and various other contaminants. Disinfection methods like ozonation and
chlorination fail to curtail these menace, often generating harmful by-products in
this process. Photocatalysis, a subsidiary of advanced oxidation processes might
have an important role to play in water decontamination. They are effective, do not
generate by-products, and provide complete inactivation against these MDR strains
and pollutants. The already existing photocatalysts like Titanium Dioxide and Zinc
Oxide are being depleted to their core. So, newer and novel photocatalysts need to
be developed with a more proficient, eco-friendly and biocompatible approach. This
discussion aims to have a closer look at the existing disinfection techniques and the
emerging players in the field of photocatalysis.
