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 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

OSU team develops process to clean coal mine drainage and extract rare earth elements

Green Car Congress

In an open-access paper in the journal Environmental Engineering Science , the team reports that the process successfully cleaned clean coal mine drainage while producing rare-earth elements in samples from various rivers across Ohio, Pennsylvania, and West Virginia. Coal mine drainage (CMD) impairs tens of thousands of kilometers of U.S.
