Bio-energy conversion with carbon capture and utilization (BECCU): integrated biomass fermentation and chemo-catalytic CO 2 hydrogenation for bioethanol and formic acid co-production

Green Chemistry, vol. 23, pp. 9860–9864

Abstract

Joining bio- and chemo-catalysis: whole-cell fermentation of glucose to ethanol is combined with in situ hydrogenation of the by-product CO 2 to formic acid using a tailored Ru-catalyst in a water–tetradecane biphasic system.
