Abstract

A heterostructure of graphitic carbon nitride/niobium oxide (g-C₃N₄/Nb₂O₅) was synthesised by hydrothermal treatment. Morphological and structural properties show an orthorhombic phase of Nb₂O₅ with evenly dispersed crystalline nanoparticles having an average diameter of 53 nm coexisted with g-C₃N₄ to form a heterostructure. Photoluminescence studies revealed minimum recombination rate compared to the bare g-C₃N₄ and Nb₂O₅ thus showing improved charge separation of the heterostructure. This work shows the potential of this material in water splitting and water treatment.
