Enhanced photocatalytic activity of brown H4Nb6O17/g-C3N4 composite for visible-light driven H2O2 production

Abstract

A novel form of brown H4Nb6O17 was synthesised by annealing niobate nanoscrolls at 300 °C. A composite heterojunction between this brown niobate and g-C3N4 was formed, and shown to have enhanced photocatalytic activity for the ORR and H2O2 production of 1.8 μmol after 3 hours. The formation of a heterojunction between the two components was shown to alter the chemical environment and suppress the PL signal, and a band diagram of the system is proposed based on our results.
