Abstract:
Selective local N-doped TiO(2) electrodes were fabricated using a pulsed laser deposition method. Different from the uniform nitrogen-doping in TiO(2) electrodes showing the diminution of IPCE in the UV light region, the inner nitrogen-doped TiO(2) electrode uniquely enhanced IPCE in the UV light region significantly (up to 95% at 320 nm, 1.23 V vs. SHE).
