First Time

The Ni-MOF as co-catalyst has been in-situ introduced on the surface of ZnO photoelectrode by chemical etching method for the first time, and the unique organic/inorganic heterostructure (Ni-MOF/ZnO) was applied for photoelectrochemical water splitting. The Ni-MOF could work as special co-catalyst to improve the kinetic and charges separation of ZnO electrode, and the photocurrent density of Ni-MOF/ZnO has increased to about 1.8 times than that of bare ZnO. The IPCE value of Ni-MOF/ZnO has been enhanced up to 11% (355[Formula: see text]nm, 0.5[Formula: see text]V vs Ag/AgCl). The proposed mechanism of charges transfer has been also discussed in-depth, according to the photoelectrochemical performance.

Pec Water Splitting

We synthesized Ni/Si-codoped TiO2 nanostructures for photoelectrochemical (PEC) water splitting, by electrochemical anodization of Ti-1Ni-5Si alloy foils in ethylene glycol/glycerol solutions containing a small amount of water. The effects of annealing temperature on PEC properties of Ni/Si-codoped TiO2 photoanode were investigated. We found that the Ni/Si-codoped TiO2 photoanode annealed at 700 °C had an anatase-rutile mixed phase and exhibited the highest photocurrent density of 1.15 mA/cm2 at 0 V (vs. Ag/AgCl), corresponding to a photoconversion efficiency of 0.70%, which was superior to Ni-doped and Si-doped TiO2. This improvement in PEC water splitting could be attributed to the extended light absorption, faster charge transfer, possibly lower charge recombination, and longer lifetime.
