Positive onset potential and stability of Cu 2 O-based photocathodes in water splitting by atomic layer deposition of a Ga 2 O 3 buffer layer

Year: 2015

Type: article

Abstract: The improved energy band alignment of Pt/TiO 2 /Ga 2 O 3 /Cu 2 O structure results in a positive onset potential of ∼1 V vs. RHE and a stable cathodic photocurrent under appropriate TiO 2 deposition temperature.
