英文摘要cocatalysts have been extensively used to promote water oxidation efficiency in solar-to-chemical energy conversion, but the influence of interface compatibility between semiconductor and cocatalyst has been rarely addressed. here we demonstrate a feasible strategy of interface wettability modification to enhance water oxidation efficiency of the state-of-the-art coox/ta3n5 system. when the hydrophobic feature of a ta3n5 semiconductor was modulated to a hydrophilic one by insitu or exsitu surface coating with a magnesia nanolayer (2-5nm), the interfacial contact between the hydrophilic coox cocatalyst and the modified hydrophilic ta3n5 semiconductor was greatly improved. consequently, the visible-light-driven photocatalytic oxygen evolution rate of the resulting coox/mgo(in)-ta3n5 photocatalyst is ca. 23 times that of the pristine ta3n5 sample, with a new record (11.3%) of apparent quantum efficiency (aqe) under 500-600nm illumination.
