Summary: In this study, a high surface area nanoporous carbon derived from MOF-5 was used as a hard template for the synthesis of TiO2 nanoparticles by nanocasting. The interconnected mesoporous network of the carbon template led to the formation of brookite and anatase TiO2 with highly developed mesoporous and macroporous structures. Furthermore, the fabricated brookite and anatase showed enhanced photocatalytic efficiency in visible light due to increased light harvesting ability and reduced band gap energy.

Summary: The study presents a synthetic strategy to fabricate Cu-doped TiO2 hollow nanostructures for visible light responsive photocatalysis. The Cu-doped TiO2 photocatalysts exhibit excellent photocatalytic performance for phenol degradation under visible light conditions. The preparation method involves sol-gel coating, ion exchange, calcination, and acid leaching processes. The superior photocatalytic performance is attributed to the uniformly doped Cu2+ ions, narrow bandgap, and more reactive TiO2 surface.

Summary: The research shows that CuOx-rutile is more suitable for the oxidation of ammonia gas under visible light compared to CuOx-anatase, contrary to previous beliefs. Further analysis revealed that the interaction between CuOx and TiO2 differs significantly in different crystal phases, resulting in distinct directions of charge transfer.
