RESUMEN

We report here the hierarchical construction of a molecular Co(II)-salicylaldimine catalyst and an in situ derived In2S3 semiconductor in a MOF@In2S3 heterojunction through sequentially controllable in situ etching and post-synthetic modification for photocatalytic hydrogen production from formic acid. The enhanced catalyst stability and facilitated charge carrier mobility between the In2S3 photosensitizers and Co catalyst realize a superior H2 production rate of 18 746 µmol g-1 h-1 (selectivity > 99.9%) with a turnover number (TON) of up to 6146 in 24 h (apparent quantum efficiency of 3.8% at 420 nm), indicating a 165-fold enhancement over that of the pristine MOF. This work highlights a powerful strategy for synergistic Earth-abundant metal-based MOF photocatalysis in promoting H2 production from FA.
