Device Purifies Air and Creates Energy All at the Same Time

In Belgium, researchers have engineered a device that uses sunlight to purify polluted air and produce hydrogen gas that can be stored and used for power. "We couple both processes together in one device," Sammy Verbruggen, a professor of bioscience engineering at the University of Antwerp, told Live Science. "Hydrogen production on one side and air purification on the other side." Verbruggenis working with two teams of researchers who had been separately investigating both processes for years. At the University of Antwerp, the scientists had been testing different ways of combing light energy with nanomaterials to purify air. At the University of Leuven, another team had been working on a tiny fuel cell with a membrane that could produce hydrogen gas from water.
