New stable water-splitting catalyst doesn’t require expensive iridium

Green Car Congress

Researchers have developed a nickel-stabilized, ruthenium dioxide (Ni-RuO 2 ) anode catalyst for proton exchange membrane (PEM) water electrolysis. The Ni-RuO 2 catalyst shows high activity and durability in acidic OER for PEM water electrolysis. Illustration by Zhen-Yu Wu. 2 , suggesting potential for practical applications.

Virginia Tech team develops process for high-yield production of hydrogen from xylose under mild conditions

Green Car Congress

A team of Virginia Tech researchers, led by Dr. Y.H. In the process, hydrogen is produced from xylose and water in one reactor containing 13 enzymes, including a novel polyphosphate xylulokinase (XK). Support for the current research comes from the Department of Biological Systems Engineering at Virginia Tech.

Virginia Tech researchers develop high-energy-density sugar “biobattery”, an enzymatic fuel cell

Green Car Congress

A Virginia Tech research team led by Dr. Y.H. The sugar battery combines maltodextrin, a polysaccharide made from partial hydrolysis of starch with air to generate electricity and water as the main byproducts. This enzymatic fuel cell is based on non-immobilized enzymes that exhibit a maximum power output of 0.8?mW?cm

Artificial enzymatic pathway delivers 1,000-fold enhancement in H2 produced by biological water splitting; more than 1g H2/L/h

Green Car Congress

Researchers from Virginia Tech developed an in vitro artificial enzymatic pathway that can produce hydrogen at extremely high rates by splitting water energized by carbohydrates (e.g., It is highly expected that green, cost-competitive, distributed H 2 will be produced via water splitting powered by solar energy directly or indirectly.
