Novel single-site gold WGS catalysts may offer pathway to lower-cost production of hydrogen, fuels and chemicals

Green Car Congress

A team of researchers from universities and national laboratories led by Tufts University has developed catalysts composed of a unique structure of single gold atoms bound by oxygen to several sodium or potassium atoms and supported on non-reactive silica materials. This single-site gold species is active for the low-temperature (.
