The organic-inorganic composites F70-TiO, based on fullerene with carboxyl group derivatives and TiO semiconductor, have been designed and constructed to become an optical-functional photocatalyst via the facile sol-gel method. The composite photocatalyst obtained shows excellent photocatalytic activity for the high-efficiency conversion of benzylamine (BA) to N-benzylidene benzylamine (NBBA) with air pressure at a normal temperature under visible light irradiation. By optimizing the composition, the composites with the 1:15 mass ratio of F70 and TiO, denoted as F70-TiO(1:15), demonstrated the highest reaction efficiency for benzylamine (>98% conversion) to N-benzylidene benzylamine (>93% selectivity) in this study.

In this study, tetrathiafulvalene-3,4,5,6-tetrakis(4-benzoic acid) (HTTFTB) is an ideal electron-rich organic material and has been introduced into TiO for promoting photocatalytic H production under visible light irradiation. Notably, the optimized composites demonstrate remarkably enhanced photocatalytic H evolution performance with a maximum H evolution rate of 1452 μmol g h, which is much higher than the prototypical counterparts, the common dye-sensitized sample (denoted as HTTFTB-5.
