A highly proton-conducting silica film (thickness, 150 nm) was successfully fabricated by combination of template synthesis with a nonionic surfactant and subsequent oxygen plasma treatment. This ultrathin silica film is mechanically and thermally stable and possesses abundant silanol groups in the nanopore. It exhibited proton conductivities greater by 1-2 orders of magnitude than those of the corresponding heat-treated silica film in humid air.
