Multilayer Ta3N5 hollow sphere-nanofilms with precisely tunable numbers of layers are successfully fabricated by the combination of oil-water interfacial self-assembly strategy and the controllable sol-gel reaction of precursors. The photoelectrochemical water splitting properties of the as-obtained Ta3N5 hollow sphere-nanofilms are significantly enhanced and found to be highly dependent on the layer numbers of the nanofilms.
