Researchers at the Institute of Nano Science and Technology (INST) have developed a novel light-driven nano-catalyst that could make the manufacturing of medicines and industrial chemicals cleaner, faster and more energy efficient by reducing dependence on toxic solvents and high-temperature processes.
The research team developed a hybrid nanocomposite by combining gold and palladium nanoparticles with a light-absorbing molecule called BODIPY. The material functions as a light-powered catalyst, using light energy to accelerate chemical reactions more efficiently than conventional catalytic systems.
According to the Ministry of Science and Technology, the technology could help industries reduce pollution, energy consumption and the use of harmful chemicals in manufacturing processes.
The study, published in the journal Nanoscale, explains that gold nanoparticles in the system absorb light energy and transfer it to the BODIPY molecule, which then passes the energy to palladium — the active catalyst driving the chemical reaction.
Researchers said the combined interaction of gold, BODIPY and palladium creates a more efficient catalytic process than the three components could achieve individually.
The nano-catalyst allows reactions to occur under milder and environmentally friendly conditions, including the use of water instead of toxic solvents and light instead of energy-intensive heating systems.
The technology was developed by Dr. Prakash P. Neelakandan and is expected to support cleaner and more cost-effective production of medicines and industrial chemicals.
Scientists said the development could contribute to sustainable industrial practices, lower energy use and improved access to affordable green technologies in the long term.
