Today, wastewater treatment is becoming more sustainable thanks to the development of supramolecular photocatalysts that use the power of sunlight to purify water. These new photocatalysts, developed by scientists, can break down pollutants in water more efficiently than traditional wastewater treatment methods. They can also be used to break down organic pollutants such as dyes, phenols, and pharmaceuticals that are commonly found in wastewater. The photocatalysts are composed of two parts: a porous material that can absorb light and a photosensitizer that is activated by the light. This process produces free radicals that break down the pollutants, making the water clean and safe to use. In addition, the photocatalysts can be reused multiple times, making them an environmentally friendly option for wastewater treatment. With the help of supramolecular photocatalysts, wastewater treatment can now be more efficient and cost-effective.
