A team of researchers from Tufts University, the University of Wisconsin-Madison and Harvard University report that alkali ions (sodium or potassium) added in small amounts activate platinum adsorbed on alumina or silica for the low-temperature water-gas shift (WGS) reaction (H 2 O+CO→ H 2 +CO 2 ) used for producing hydrogen.

As reported in Nature Energy , bismuth vanadate (BiVO 4 ) electrodes with more bismuth on the surface (relative to vanadium) generate higher amounts of electrical current when they absorb energy from sunlight. This photocurrent drives the chemical reactions that split water into oxygen and hydrogen.

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 (.
