Enhanced photocatalytic activity of BiVO4 by co-grafting of metal ions and combining with CuBi2O4

- Fe ion graft on BiVO4 increased the H2O2 formation but decreased the O2− formation.
- Photocatalytic activity of BiVO4 was enhanced by grafting both Fe3+ and CoPi.
- Combination with a p-type semiconductor CuBi2O4increased photocatalytic activity.
- Grafting of Fe3+ on CuBi2O4 and CoPi on BiVO4 enhanced the activity of the composite.
