This work reports a novel approach to patterning copper nanoparticles on a Cu2O substrate by a photo-electroreduction reaction with the aid of scanning electrochemical microscopy in direct mode. The concept is based on the localized cathodic current flux produced when applying both negative potentials and light irradiation to p-type semiconductors. The patterns can be tuned by modifying the deposition potential, duration time and illumination intensity, and have been characterized by scanning electron microscopy, energy-dispersive X-ray analysis and micro-Raman spectroscopy.
