Metal carbides capped with monolayer quantities of precious metals can serve as active hydrogen evolution catalysts, according to a study conducted at the University of Delaware (J. Am. Chem. Soc., DOI: 10.1021/ja208656v). The work may lead to low-cost substitutes for platinum-based electrolyzers and fuel-cell catalysts by drastically reducing the required loading of expensive metals. Electrolyzers . . .
