Abstract

Abstract A hybrid organic–inorganic catalyst of polyheptazine and TiO 2 nanotubes was obtained by polymerization of polyheptazine directly on the surface of layered titanate nanotubes (TiNT) at 400 °C; leading to a phase transition from TiNT to TiO 2 anatase. This method induces the polymerization in-between the layers of TiNTs, in contrast to what happens on commercial TiO 2 nanoparticles (P25), for which polymer adsorption occurs only onto the outer surface. As a result, the hybrid materials exhibit enhanced physical–chemical properties, resulting in improved photocatalytic response; the methylene blue degradation was 1.28-times higher using the hybrid polyheptazine-TiO 2 nanotubes as a photocatalyst, in comparison to the use of polyheptazine-P25. Besides, polyheptazine-TiO 2 nanotubes show higher photo-electrocatalytic activity than TiNTs, whereas polyheptazine-P25 exhibits lower activity than P25. The lower band-gap energies, zeta potentials and higher surface area make the polyheptazine-TiO 2 nanotubes more efficient photocatalysts under visible light in comparison to P25-based nanoparticles.
