(a) H2 production from Pt@CdS over 3 h of irradiation of a mixture of BuOH, ADH, NAD+, and β-alanine. (b) BA and 2-EH yields with and without β-alanine, as measured by 1H NMR. (c) H2 production after 3 h of reaction with simulated ABE feedstock, instead of pure butanol. (d) Product distribution from this mixture. All error bars indicate one SD from triplicate measurements.
