A team of researchers from IIT-Bombay, led by Prof Arnab Dutta from the Department of Chemistry, has made strides in the field of green hydrogen production by exploring a cost-effective alternative to noble metals as catalysts. The team focused on the use of cobaloxime, a molecular catalyst that is water-soluble, stable in air, and cheaper than noble metals like platinum and palladium. By modifying the molecular structure of cobaloxime with natural amino acids and vitamins, they have increased hydrogen production while maintaining energy efficiency. The research aims to address the high cost associated with green hydrogen production, particularly for applications like green steel, by making the process more efficient and cost-effective. Cobaloximes, although cheaper and easily synthesizable, present challenges in industrial applications due to their complexity. To overcome this, the researchers are working on modifying the structure of cobaloximes to enhance stability, efficiency, and durability in an industrial setting. The team's findings indicate that cobaloxime catalysts perform well in various electrolyser conditions, including alkaline and proton exchange membrane electrolysers. They are currently developing an updated version of the cobaloxime template to be applicable in heterogeneous conditions, crucial for industrial setups. The ultimate goal is to lower the cost of green hydrogen production, especially for the production of green steel, by using renewable energy to power the electrolysis process.
