Light-Powered Device Cleans Air and Makes Fuel

May-10-17 Researchers have created a small, light-powered device able to purify air as it produces hydrogen gas.

The device spun out of the discovery that water molecules could be pulled directly from the air to create hydrogen gas—without the need for liquid water. The team from KU Leuven took this discovery a step further, with the realization that polluted air works even better.

The device features a pair of chambers separated by a membrane. Air is purified on one side of the membrane by using a light-activated nanomaterial to convert the organic pollutants to “less harmful compounds.” Meanwhile, hydrogen atoms that are separated from the molecules travel through the membrane, where they react with H2 gas and can be stored for use as fuel.
