Hydrogen Evolution from Water/Alcohol Mixtures: Effective In Situ Generation of an Active Au/TiO2 catalyst

Authors


Abstract

Gold standard: Au/TiO2 catalysts, easily prepared in situ from different Au precursors and TiO2, generate hydrogen from water/alcohol mixtures. Different alcohols, and even glucose, can serve as sacrificial reductants. The best system produces hydrogen on a liter scale, and is stable for more than two days. Deuteration studies show that proton reduction is likely the rate-limiting step in this reaction.
