Novel fabrication of a nitrogen-doped mesoporous TiO2-nanorod titanate heterojunction to enhance the photocatalytic degradation of dyes under visible light

Abstract

A one-pot synthesis of a mesoporous nitrogen-doped TiO₂-nanorod titanate heterojunction was developed. The reusable prepared heterogeneous photocatalyst exhibited an enhanced photocatalytic degradation of 10 mg L⁻¹ methylene blue dye after 60 min of visible light irradiation, which was attributed to the large surface area, high mesoporosity and effective separation of photo-induced charge carriers.
