EduAsiaNews, New Delhi — Researchers at the Indian Institute of Technology (IIT) Guwahati have successfully developed a new MXene-based material capable of simultaneously producing clean hydrogen fuel and converting seawater into drinking water using solar energy. This groundbreaking discovery was published in the prestigious scientific journal Advanced Functional Materials on March 17, 2026, and has drawn widespread attention from the global scientific community for offering answers to two of humanity’s greatest crises: dependence on fossil fuels and the scarcity of clean water.
The research was led by Prof. PK Giri of the Department of Physics at IIT Guwahati, alongside two of his doctoral students, Koushik Ghosh and Sanjoy Sur Roy. MXene is known as a two-dimensional material with high electrical conductivity, but generally has a low active surface area that limits its catalytic capability. To overcome this limitation, the research team engineered the material into an ultrathin nanoribbon structure to enhance charge transport and expand the active surface area. Ruthenium atoms were then incorporated into oxygen-deficient sites to further boost catalytic efficiency through strengthened metal-support interactions.
In desalination trials, the MXene material was integrated into a three-dimensional “Janus evaporator” device designed to float on water and minimise energy loss by heating only the surface layer. Under standard sunlight exposure, the system achieved an evaporation rate of approximately 3.2 kilograms per square metre per hour and was tested continuously for five days in saline water without any salt accumulation. The resulting water met international drinking water quality standards, making it a viable solution for regions facing freshwater scarcity.
Prof. PK Giri underscored the immense potential of the discovery. “Two-dimensional layered MXene material is a wonder material with multifunctional applications. This research demonstrates sustainable development of clean hydrogen energy and drinking water solutions using defect engineering in ultrathin MXene. With enhanced high performance and stability, the developed material has potential for commercial use,” he said. On the hydrogen production front, the material recorded an exceptionally low hydrogen evolution reaction overpotential of just 12 mV, surpassing commercial Pt/C electrodes and highlighting its outstanding electrocatalytic performance.
The discovery is considered strategically significant for developing nations, including India, which face the dual pressures of growing energy demand and water crisis. Potential applications of the system span transportation, industrial energy systems, and decentralised water treatment, contributing to sustainable development while reducing environmental impact. Experts describe this innovation as a major breakthrough, as a single material is able to address two sustainability challenges at once — something never previously achieved at this scale and level of efficiency. **
