• Researchers at IIT Guwahati developed a novel MXene based material capable of producing hydrogen fuel through water electrolysis with exceptional efficiency and stability.

• The material exhibits an ultralow hydrogen evolution overpotential of only 12 millivolt, outperforming conventional platinum based catalysts used in commercial hydrogen production systems.

• It also enables solar powered desalination of seawater, providing a cost effective and sustainable method for producing safe drinking water in water scarce regions.

• Scientists engineered ultra thin ribbon like structures and introduced metal atoms to enhance surface area, charge transport, and catalytic performance significantly.

• Advanced computational modelling was used to understand atomic level improvements, confirming enhanced catalytic activity due to strong interactions within the material structure.

• The material showed excellent performance under simulated sunlight, demonstrating strong photothermal conversion and long term stability with minimal loss in efficiency.

• It was integrated into a floating device that reduces energy loss and achieved high evaporation rates without salt accumulation over extended testing periods.

• This dual functional innovation has strong potential for commercial applications in clean energy production, water purification, transportation, and sustainable industrial processes.
