Luwei Chen, Armando Borgna and colleagues at the A*STAR Institute of Chemical and Engineering Sciences have developed a long-lived catalyst in a new first step in viable ethanol fueled small-scale on-board hydrogen generators. Hydrogen is a renewable resource with the potential to power everything from households to cars, but its use is currently limited by […]

James Tour’s lab at Rice University has turned molybdenum disulfide’s two-dimensional form into a nanoporous film that can catalyze the production of hydrogen. The Rice University scientists also report the molybdenum disulfide film can be used for electrical energy storage in a capacitor. The versatile molybdenum disulfide compound classified as a dichalcogenide is inert along […]

Scientists at Ecole Polytechnique Fédérale de Lausanne (EPFL) have developed a new and efficient way of producing hydrogen fuel from sunlight and water. Connecting together solar cells made with a mineral called perovskite and the team’s low cost electrodes achieves a 12.3 percent conversion efficiency from solar energy to hydrogen. The profusion of tiny bubbles […]

Stanford University scientists have developed a low-cost, emissions-free device that uses an ordinary AAA battery to produce hydrogen by water electrolysis. Unlike other water splitters that use precious-metal catalysts, the electrodes in this device are made of inexpensive and abundant nickel and iron. Professor Hongjie Dai and colleagues have developed a cheap, emissions-free device that […]

Rutgers researchers have developed a technology using carbon nanotubes in place of platinum to produce hydrogen. The technology could overcome platinum’s major cost barrier to making clean-burning hydrogen fuel. The new technology is a novel catalyst that performs almost as well as cost-prohibitive platinum for so-called electrolysis reactions, which use electric currents to split water […]
