Oxygen Content-Controllable Synthesis of Non-Stoichiometric Silicon Suboxide Nanoparticles by Electrochemical Anodization.

A facile route to producing non-stoichiometric silicon suboxide nanoparticles (SiO NPs, 0 < x < 1) with an adjustable oxygen content is proposed. The process is based on electrochemical anodization involving the application of a strong electric field near the surface of a Si electrode to directly convert the Si electrode into SiO NPs. The difference in ion mobility between oxygen species (O and OH), formed during anodization, causes the production of non-stoichiometric SiO on the surface of the Si while, simultaneously, fluoride ions in the electrolyte solution etch the formed SiO layer, generating NPs under the intense electric field.
