Abstract

Abstract : Novel, brown H4 Nb6 O17, was synthesised and a composite heterojunction with g-C3 N4 was formed, showing enhanced photocatalytic activity for H2 O2 production. Abstract : A novel form of brown H4 Nb6 O17 was synthesised by annealing niobate nanoscrolls at 300 °C. A composite heterojunction between this brown niobate and g-C3 N4 was formed, and shown to have enhanced photocatalytic activity for the ORR and H2 O2 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.
