Enhanced photoelectrochemical water oxidation by ZnxMyO (M ¼ Ni, Co, K, Na) nanorod arrays
Journal ArticleThe present work reports a facile approach to the one-pot solution growth of vertically
aligned, doped ZnO nanorod (NR) arrays by chemical bath deposition (CBD). The effects of
dopant ions on the final morphologies, electronic band structures and donor densities of
ZnO NRs were examined. With the introduction of dopants, the optical band gap energies
of the samples were reduced. The photoelectrochemical (PEC) water splitting performances
of the doped ZnO NRs were tested. When compared with pristine ZnO NRs, the doped ZnO
NRs demonstrated an improvement of at least 15% in the PEC water splitting activity. Nadoped ZnO NRs was the most efficient photoanode, where its photocurrent density was 2.1
times greater than that of pristine ZnO NRs. The mechanism for improved PEC performance was proposed
