Green ammonia will play an important function in decarbonized energy systems but its production places a high burden on limited renewable resources in land-constrained countries. Here we propose the offshore production of green ammonia, which can increase energy security without land competition.
Synthesis can be used to harness excited states and molecular functional materials. Supramolecular chemistry can provide an additional dimension of control to the excited states and expand the library of excited-state functional materials.
Cross-coupling between two different C–H bonds with the release of hydrogen is a powerful yet challenging transformation. Catalytic methods that harness photo- or electrochemistry facilitate thermodynamically unfavourable coupling reactions under mild conditions. This Perspective outlines strategies based on photoinduced hydrogen-atom transfer for the cross-coupling of various hydrocarbons.
