Wirelike catalysts of mixed-phase TiO2(B)/anatase TiO2, bare anatase TiO2 and TiO2(B) are synthesized via calcining precursor hydrogen titanate obtained from hydrothermal process at different temperatures between 450 and 700 degrees C. Under visible light irradiation, mixed-phase TiO2(B)/anatase TiO2 catalysts exhibit enhanced photocatalytic activity in comparison with pure TiO2(B) and anatase TiO2 toward selective oxidation of benzylamines into imines and the highest photocatalytic activity is achieved by TW-550 sample consisting of 65% TiO2(B) and 35% anatase. The difference in photocatalytic activities of TiO2 samples can be attributed to the different adsorption abilities resulted from their crystal structures and interfacial charge separation driven by surface-phase junctions between TiO2(B) and anatase TiO2. Moreover, the photoinduced charge transfer mechanism of surface complex is also proposed over mixed-phase TiO2(B)/anatase TiO2 catalysts. Advantages of this photocatalytic system include efficient utilization of solar light, general suitability to amines, reusability and facile separation of nanowires catalysts. (C) 2015 Elsevier B.V.
