Guwahati, January 5 (NationPress) In a groundbreaking advancement for clean energy and environmental protection, scientists at the Indian Institute of Technology (IIT) Guwahati have engineered a photocatalytic material capable of transforming carbon dioxide (CO₂) into methanol fuel using sunlight.
As the reliance on petroleum-derived fuels remains a primary contributor to CO2 emissions, leading to environmental strain and global warming, this research, published in the Journal of Materials Science, tackles the critical issue of fulfilling the increasing energy demands without further damaging our planet.
This innovative technology has the potential to be utilized across various industries, including thermal power plants, cement production, steel manufacturing, and petrochemical refineries, facilitating the shift towards a circular carbon economy and a more sustainable energy landscape.
According to Prof. Mahuya De from the Department of Chemical Engineering at IIT Guwahati, “The current study aims to alleviate environmental challenges while simultaneously promoting green energy. Converting CO2 into cleaner fuel with solar energy represents a promising approach in this direction.”
Researchers globally have been striving to tackle this urgent challenge using graphitic carbon nitride, a cost-effective, metal-free, and non-toxic material. However, previous efforts have faced hurdles, including rapid energy dissipation and inadequate fuel production.
The IIT Guwahati research team has successfully combined graphitic carbon nitride with few-layer graphene. This ultra-thin carbon material, known for its exceptional electrical conductivity and energy transfer properties, significantly reduces energy loss in the catalyst.
The findings indicate that the integration of few-layer graphene enhances the photocatalytic energy retention of carbon nitride under sunlight exposure, maintaining catalyst activity for extended periods, which leads to improved light absorption and enhanced charge generation.
Among the tested composites, the catalyst with a 15 weight percentage of graphene exhibited the highest efficiency in converting CO2 to methanol, showcasing remarkable stability—an essential characteristic for practical applications.
Looking ahead, the research team is focused on scaling this technology for real-world applications and aims to create a durable photocatalytic system capable of converting industrial CO2 emissions into clean fuels.
