The hydrogenation of CO2 to form methane has been known for over a century. However, given increased interest in small-molecule activation for energy storage, and improved catalysts and understanding of the process, it is worthwhile to look again at the reaction. This Perspective discusses recent work on the fundamentals of the Sabatier reaction and also the potential for large-scale applications.
The electrochemical reduction of carbon dioxide to fuels and feedstocks has received increased attention over the past few years. In this Review, Roldan Cuenya and co-workers discuss strategies to achieve high selectivity towards multicarbon products via rational catalyst and electrolyte design.
Desalination processes generally leave brine as a by-product, which is then discharged back into the environment. This Perspective looks at recent procedures for using this brine instead as resource for the production of hydrochloric acid and sodium hydroxide through direct electrosynthesis.
Optimization of catalytic stereoselectivity for new substrates often requires a time consuming experimental process, and high-accuracy molecular modelling remains intractable for comprehensive virtual screening. Now, highly enantioselective rhodium hydrogenation catalysts have been identified using a rapid computational transition-state analysis protocol and then experimentally verified.
Amide bond formation is a hugely important reaction in organic synthesis. This Perspective examines the factors that influence the choice of reaction conditions for this process, comparing widely used stoichiometric reagents with catalysts. The authors draw on both academic and industrial data and focus on the efficiency, scope and sustainability of the various approaches.
Production of industrial chemicals from renewable biomass feedstock plays an important role in addressing limited fossil fuel resources, climate change and environmental problems. This Review provides a comprehensive overview of biological and chemical routes for the synthesis of industrial chemicals derived from key precursor metabolites of central carbon metabolic pathways, and visualizes the results in a global bio-based chemicals map.
