摘要：Nowadays, the preparation of CuBi2O4 powder as photocatalyst has been studied intensively. However, there have been few reports on CuBi2O4 films with uniform coverage, large surface area and excellent photoelectrochemical (PEC) properties. Therefore, this work reports a novel two-step synthesis method to prepare honeycomb network-like CuBi2O4 films for efficient photoelectrochemical water splitting. A pearl-like CuBi2O4 film was prepared by electrodeposition method first, and then using pearl-like CuBi2O4 films as framework to prepare honeycomb network-like CuBi2O4 films. The photocurrent of pearl-like CuBi2O4 films is - 0.59 mA at - 0.8 V vs. RHE under simulated sunlight, which of honeycomb network-like CuBi2O4 films is - 1.22 mA at -0.8V vs. RHE, which is 1.90 times improvement than pearl particle CuBi2O4 films. This research provides a unique insight into the in-depth exploration of CuBi2O4 films as photocathodes for efficient photoelectrochemical water splitting.
