Chemical engineers in Switzerland have invented a solar-powered artificial leaf. Their solar-powered, transparent and porous electrode turns water from its gaseous state in the air into hydrogen fuel.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 H2. The electrode's substrate is a three-dimensional mesh of felted glass fibers, a type of glass wool, which is essentially quartz. The silicon oxide fibers are then fused together at high temperatures ...Den vollständigen Artikel lesen ...
