摘要：
Zinc oxide films on AISI 304 stainless steel were prepared by electrochemical deposition using slightly acidic zinc acetate solutions under galvanostatic conditions. The prepared films were characterized by X-ray diffraction, Fourier - transform infrared spectroscopy, scanning electron microscopy and photovoltammetry analysis. It was established that as-deposited ZnO films consist of lamellar particles with intercalated CH3COO- ions. It was determined that ZnO films show n-type behavior, the incident photon-to-current efficiency (IPCE) being 2.0 % at +0.6 V in 0.1 M K2SO4 solution. The observed steady-state photocurrents increased upon heat treatment at 673 K of as-deposited ZnO samples and in the presence of methanol in supporting electrolyte.
