Abstract

Simple energy-dense liquid oxygenates obtained directly from biomass e.g., fermentation ethanol, or “solar methanol”, synthesised from renewable hydrogen (via PV-driven water electrolysis) and recycled carbon dioxide, could provide the basis of an energy cycle that is climate-neutral and promotes long-term sustainability in industrial chemical processing. The development of new earth-abundant heterogeneous (photo-)catalysts and associated reaction engineering promoting hydrogen release (by steam-reforming) and insertion (by CO₂ hydro-deoxygenation) under mild conditions will be pivotal to its success. This review anticipates the key methodologies involved in future bio-refineries and forecasts the increasing role therein of modular and portable low-power solar concentrators as renewable (photonic and thermal) resources. The techno-economic prospects for oxygenates like acetaldehyde, ethylene glycol, and glycerol, are also considered based on their reactivity (C₂) and/or a pre-existent supply glut in need of valorisation (C₃). Many examples highlighting the growing importance of computational (DFT and microkinetic) modelling in catalyst development are presented.

期刊介绍： Catalysis Today focuses on the rapid publication of original invited papers devoted to currently important topics in catalysis and related subjects. The journal only publishes special issues (Proposing a Catalysis Today Special Issue), each of which is supervised by Guest Editors who recruit individual papers and oversee the peer review process. Catalysis Today offers researchers in the field of catalysis in-depth overviews of topical issues. Both fundamental and applied aspects of catalysis are covered. Subjects such as catalysis of immobilized organometallic and biocatalytic systems are welcome. Subjects related to catalysis such as experimental techniques, adsorption, process technology, synthesis, in situ characterization, computational, theoretical modeling, imaging and others are included if there is a clear relationship to catalysis.
