Finding a solution for both cleaning up polluted air and generating clean energy is one of the world's top priorities and seldom do scientists attempt to tackle these problems with one single piece of technology. According to Engadget, however, researchers in Belgium have been trying to do just that.
Their device uses a process called heterogeneous photocatalysis which uses light and a semiconductor to trigger a chemical reaction in two separate areas. This reaction takes polluted air and simultaneously purifies it on one side while generating hydrogen on the other. This hydrogen could be stored to be used for energy later.
Although their device is currently just a proof-of-concept, it is a fantastic sign of potential things to come.
