Researchers from the University of Antwerp and KU Leuven have successfully come up with a process that can produce hydrogen from polluted air. The device functions only in the presence of sunlight.

According to Ku Leuven News, the device used for this process has two compartments which are separated by a membrane. Polluted air is purified on one side while on the other side, hydrogen gas is produced which can be used as a fuel.

One of the most important aspects of the device is the membrane, for which the researchers have used specific nanomaterials.

Explaining the use of nano-catalysts, Professor Sammy Verbruggen (UAntwerp/KU Leuven), explains, “These catalysts are capable of producing hydrogen gas and breaking down air pollution.”

“In the past, these cells were mostly used to extract hydrogen from water. We have now discovered that this is also possible, and even more efficient, with polluted air.”
