which provides pathways to maximize daylight utilization by operating even under low solar irradiance. Under 1 sun irradiation, the perovskite–BiVO4PEC tandems sustain bias-free syngas production coupled to water oxidation for three days. The devices present solar-to-H2and solar-to-CO conversion ef...
Schematic representation of the pathways for ethanol production. In the direct pathway (orange), acetyl-CoA is converted into ethanol via acetaldehyde by alcohol dehydrogenase (ADH). Ethanol production via the indirect pathway (red) involves reduction of acetate into acetaldehyde by aldehyde:ferredoxin...

The production of feed for an olefin hydration zone is improved by integrating treatment of an alcohol containing stream from a fermentation zone into an alcohol separation section.
, providing a useful platform to support the co-catalysts and improve the catalytic performance without affecting optical properties. As described herein, the intimate Pt/TiO2interface provides multiple sites and unique channels that facilitate the CO2activation and reaction pathways for syngas production....
board a vehicle [27,33,34]. External on-board and in-cylinder fuel reforming techniques have been identified as possible pathways to produce syngas on-board inIC enginesto improve efficiency and emissions[33]. The details of on-board fuel reforming andsyngas productionwill be covered in section...
The stability tests were performed to evaluate the photocatalytic durability of the catalyst. The SACs retained ~100% syngas production rate after three cycles (1 h per cycle) of photocatalysis (Supplementary Fig.20). The Co@Si sample with 3.4 wt%Co presents the highest CO conversion of...
Fig. 6: Reaction pathways over ZnGaOx-SAPO-34 composites. ZnGaOxoxides containing coordination unsaturated Ga3+, oxygen vacancy and zinc vacancy sites are much more active and selective in syngas conversion to light olefins. Discussion ZnGaOxspinels with similar compositions but different morphologies ...
This chapter examines the reaction pathways and the selectivity of the catalysts for the conversion of syngas to liquid hydrocarbons and ethanol fuels. Rh is by far the most active catalyst for ethanol synthesis. Co- and Fe-based catalysts exhibit excell
