Heterogeneous Catalysis
The major research activities under the Green Chemistry and Catalysis group are the development of heterogeneous catalysts for energy and environmental applications. The main design constraints involved in the rational design and development of heterogeneous catalysts include,
Use of earth-abundant elements
Use of non-toxic and non-polluting materials and processes
Use of relatively low temperature (mostly room temperature) in the entire process
Use of atmospheric pressure for the catalytic reactions
Adherence to the Green Chemistry principles
Catering to the relevant UN Sustainable Development Goals (SDG), mainly,
(a) SDG 06 - Clean Water and Sanitation
(b) SDG 07 - Affordable and Clean energy
(c) SDG 12 - Responsible Consumption and Production
(d) SDG 13 - Climate Action
