A device that can harvest water from the air and provide hydrogen fuel—entirely powered by solar energy—has been a dream for researchers for decades. Now, EPFL chemical engineer Kevin Sivula and his ...

Chemical engineers from École polytechnique fédérale de Lausanne (EPFL) have developed a solar-powered transparent, porous and conductive electrode, which uses an input stream of humid air to produce ...

The electrocatalytic hydrogen evolution reaction (HER) is one of the most efficient methods for producing green hydrogen. However, the inefficient mass transfer of hydrogen has greatly impeded HER ...
