We report here on a novel photocathode with a “donor-dye-catalyst” assembly structure for water reduction. The photoelectrocatalytic performance of the photocathode under mild conditions, with a photocurrent of -56 µA/cm2 and a Faradaic yield of 53%, is superior relative to other reported photocathodes with surface attached molecular catalysts. Detailed electron transfer analyses, based on transient absorption measurements, show that the successful application of this photocathode originates mainly from the slow back electron transfer following light excitation. The results also demonstrate that addition of the long-chain assembly to the macro-mesoporous electrode surface plays a fundamental role in providing sufficient catalyst for water reduction.
