A research team at Chalmers University of Technology in Sweden has developed a new method to produce hydrogen gas using sunlight, water, and electrically conductive plastic particles, eliminating the need for scarce and expensive platinum. This breakthrough offers a sustainable and cost-effective way to produce hydrogen, crucial for renewable energy efforts, without the environmental and health risks associated with platinum. The research, published in Advanced Materials, demonstrates the efficient production of hydrogen gas from solar energy without the use of platinum, offering a promising solution for environmentally friendly hydrogen production.
