The polarized W|BCN interface acts as a selective platform for the separation of the products of the photoreaction, TTF and protons, which has a strong positive effect on the efficiency of the WOR. The resulting cobalt oxide-organic microwire junction is as efficient as its Pt analog.Electrochemistrywater oxidationliquid/liquid interfacesphotochemistrytetrathiafulvalenehydrogen evolutionion transferartificial photosynthesistetrathiafulvalene ttfoxygen-evolutionredox mediatorttf+center-dotphotoanodesoxidationscaffoldtext::journal::journal article::research article
