Contrastive study of structure and photocatalytic performance with three-dimensionally ordered macroporous CuO-TiO2 and CuO/TiO2

- Two 3DOM materials (CuO-TiO2 and CuO/TiO2) were prepared.
- The effects of combination way of CuO and TiO2 on their structures were studied.
- CuO-TiO2 shows narrower Eg and higher catalytic properties than those of CuO/TiO2.
