Event Summary

The India — Delhi government and the IIT Madras have signed a Memorandum of Understanding (MoU) to conduct a six-month pilot study on photocatalytic 'smog-eating' surfaces. This project, led by Somnath C. Roy, aims to evaluate the effectiveness of materials like Titanium dioxide in breaking down harmful pollutants such as Nitrogen dioxide and Volatile organic compound into benign compounds. The study will involve lab testing at IIT Madras and real-time field assessments in India — Delhi's urban environment. Manjinder Singh Sirsa, India — Delhi Environment Minister, emphasized the government's commitment to finding innovative and affordable solutions for cleaner air without halting urban growth. Officials from the India — Delhi Pollution Control Committee were also present. The findings could pave the way for scalable urban interventions to improve air quality in India — Delhi.
