Researchers Develop New Lower-Cost, Efficient Catalyst for Water Gas Shift Reaction for Hydrogen Production

Green Car Congress

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.

Tuning electrode surfaces to optimize solar fuel production

Green Car Congress

Scientists have demonstrated that modifying the topmost layer of atoms on the surface of electrodes can have a remarkable impact on the activity of solar water splitting. This photocurrent drives the chemical reactions that split water into oxygen and hydrogen. —Mingzhao Liu. —Kyoung-Shin Choi.

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 (.
