IIT Madras to study 'smog-eating' surfaces to cut Delhi pollution
India Today
IIT Madras and the Delhi government have signed an MoU to study 'smog-eating' surfaces to help tackle air pollution in the capital.
The Delhi government has signed a Memorandum of Understanding (MoU) with Indian Institute of Technology Madras to conduct a six-month pilot study on photocatalytic “smog-eating” surfaces aimed at reducing air pollution in the capital.
The project will examine whether materials using Titanium Dioxide (TiO) or similar photocatalysts can reduce pollutants such as nitrogen dioxide (NO) and volatile organic compounds (VOCs), both of which contribute to urban smog.
The MoU was signed in the presence of Delhi Environment Minister Manjinder Singh Sirsa and officials from the environment department and the Delhi Pollution Control Committee. The initiative is being carried out under the leadership of Chief Minister Rekha Gupta.
According to the government, the study will explore whether photocatalytic materials can be applied to urban infrastructure such as roads, buildings and other surfaces.
These materials react under sunlight and can convert certain harmful pollutants into less harmful compounds.
“Through this study with IIT Madras, we aim to identify practical ways to apply smog-eating coatings on roads, buildings and other surfaces. If the research provides evidence that such materials can reduce pollutants like NO, it could support future interventions,” Sirsa said.
