University of California – Santa Cruz researchers show a novel ruthenium-based catalyst with markedly better performance than commercial platinum catalysts in alkaline water electrolysis for hydrogen production. The catalyst is a nanostructured composite material composed of carbon nanowires with ruthenium atoms bonded to nitrogen and carbon to form active sites within the carbon matrix. The […]

DOE/Argonne National Laboratory scientists have identified a new catalyst that uses only about a quarter as much platinum as current technology by maximizing the effectiveness of the available platinum. The Argonne chemists have published their study results in the journal Science. Platinum is a precious metal more rare than silver or gold. Renowned in the […]

University of California – Riverside (UCR) researchers have now described the development of an inexpensive, efficient catalyst material for a type of fuel cell called a polymer electrolyte membrane fuel cell. The new cell turns the chemical energy of hydrogen into electricity and is among the most promising fuel cell types to power cars and […]

Washington State University researchers have created a catalyst capable of reducing pollutants at the lower temperatures expected in advanced engines. As cars become more fuel efficient, less heat is wasted out the exhaust, which makes it harder to clean up the pollutants being emitted. The work of researchers at Washington State University, Pacific Northwest National […]

A Johns Hopkins University team of chemical engineers has drawn inspiration from the ancient Egyptian tradition of gilding to make modern-day fuel cells less expensive and more powerful. Egyptians artists at the time of King Tutankhamun often covered cheaper metals (copper, for instance) with a thin layer of a gleaming precious metal such as gold […]
