Abstract:
A novel CdSe/NiO heteroarchitecture was designed, prepared, and used as a photocathode for hydrogen generation from water. The composite films were structurally, optically, and photoelectrochemically characterized. The deposition of CdSe on the NiO film enhanced light harvesting in the visible‐light region and photoelectrochemical properties. Moreover, the CdSe/NiO photoelectrode showed superior stability both in nitrogen‐saturated and air‐saturated neutral environments. The CdSe/NiO photoelectrode after MoS 2 modification retained the stability of the CdSe/NiO electrode and exhibited higher photocatalytic and photoelectrochemical performances than the unmodified CdSe/NiO electrode. In pH 6 buffer solution, an average hydrogen‐evolution rate of 0.52 μmol h −1 cm −2 at −0.131 V (versus reversible hydrogen electrode, RHE) was achieved on a MoS 2 /CdSe/NiO photocathode, with almost 100 % faradaic efficiency.
