UT El Paso-led team designs cactus-inspired low-cost, efficient water-splitting catalyst

Green Car Congress

Researchers led by engineers at The University of Texas at El Paso (UTEP) have proposed a low-cost, cactus-inspired nickel-based material to help split water more cheaply and efficiently. Nickel, however, is not as quick and effective at breaking down water into hydrogen. who led the study.

Exeter team develops low-cost photoelectrode for spontaneous water-splitting using sunlight

Green Car Congress

Researchers at the University of Exeter (UK) have developed a novel p-type LaFeO 3 photoelectrode using an inexpensive and scalable spray pyrolysis method. The nanostructured photoelectrode results in spontaneous hydrogen evolution from water without any external bias applied with a faradaic efficiency of 30% and excellent stability.

Stanford researchers make ammonia from air and water microdroplets

Green Car Congress

Stanford researchers, with a colleague from King Fahd University of Petroleum and Minerals, have developed a simple and environmentally sound way to make ammonia with tiny droplets of water and nitrogen from the air. Water microdroplets are the hydrogen source for N 2 in contact with Fe 3 O 4. —Song et al. Song et al.

EPFL team develops low-cost water splitting cell with solar-to-hydrogen efficiency of 12.3%

Green Car Congress

Michael Grätzel at EPFL (Ecole Polytechnique Fédérale de Lausanne) in Switzerland has developed a highly efficient and low-cost water-splitting cell combining an advanced perovskite tandem solar cell and a bi-functional Earth-abundant catalyst. Splitting water requires an applied voltage of at least 1.23 V and up to 1.5

BNL Researchers develop low-cost, efficient, non-noble metal electrocatalyst to produce hydrogen from water

Green Car Congress

James Muckerman at the US Department of Energy’s (DOE) Brookhaven National Laboratory (BNL) have developed a new class of high-activity, low-cost, non-noble metal electrocatalyst that generates hydrogen gas from water. The result becomes this well-balanced Goldilocks compound—just right. —James Muckerman.
