Design of TiO<sub>2</sub>@Carbon@Prussian Blue Core–Shell Nanorod Arrays for Enhanced Photoelectrochemical Performance
The
thoughtful design of effective photoanodes has drawn significant
attention. Here, a Z-scheme core–shell TiO2@carbon@prussian
blue (TiO2@C@PB) is designed for photoelectrochemical water
splitting. TiO2@C@PB composite film has a larger absorption
range, and the band gap is decreased from 3.10 to 2.65 eV. Under illumination
conditions, the TiO2@C@PB composite photoanode achieves
a photocurrent density of 2.78 mA/cm2 at 1.23 V vs RHE,
nearly 2.5 times higher than that of pure TiO2. The enhancement
is ascribed to the suppressed recombination of photogenerated charges
facilitated by the Z-scheme heterojunction and the excellent conductivity
of carbon. This study offers an effective approach for developing
highly efficient photoelectrochemical water-splitting photoanodes
