IIT-G Breakthrough: Composite Coating Tech Boosts Green Hydrogen Production Efficiency

IIT Guwahati researchers have made a breakthrough in green hydrogen production, developing a composite coating technology that boosts the efficiency and durability of solar-driven water splitting systems. This innovative approach combines graphitic carbon nitride with a bubble-repellent hydrogel layer on porous nickel foam, resulting in 51% higher hydrogen production and 44% higher oxygen production compared to conventional methods. The team’s findings, published in the international journal Small, demonstrate the potential of this technology for next-generation clean energy systems. The coating strategy may also benefit renewable energy storage and large-scale solar-to-fuel conversion devices.
Prof. Uttam Manna and Prof. Mohammad Qureshi, leading the research, highlight the significance of this breakthrough, stating that it can be applied broadly to advance green hydrogen production. They plan to further improve water-splitting efficiency and scale up the system for larger electrodes.
The project received grant support from ANRF, the Ministry of Electronics and Information Technology, IIT Guwahati, and the Ministry of Education.
