Electrosynthesis of multicarbon products from CO2 is restricted by the proton-rich conditions in strong acids leading to unfavourable hydrogen evolution. Now a heterogeneous catalyst adlayer composed of covalent organic framework nanoparticles and cation-exchange ionomers is reported to regulate the local pH, suppressing H2 generation and promoting multicarbon formation.
