英文摘要: Highly efficient water oxidation utilizing visible photons of up to 600 nm is a crucial step in artifical photosynthesis. Here we present a highly active photocatalyst for visible-light-driven water oxidation, consisting of single-crystalline meso- and macroporous LaTiO2N (LTON) with a band gap of 2.1 eV, and earth-abundasnt cobalt oxide (CoOx) as a cocatalyst. The optimized CoOx/LTON had a high quantum efficiency of 27.1 +/- 2.6% at 440 nm, which substantially exceeds the values reported for previous particulate photocatalysts with a 600-nm absorption edge.
