Synergistic effects of SrTiO3 nanocubes and Ti3+ dual-doping for highly improved photoelectrochemical performance of TiO2 nanotube arrays under visible light

Abstract

We demonstrate that the hetero-coupling of SrTiO3 nanocubes on TiO2 nanotube arrays and Ti3+ dual-doping on both SrTiO3 and TiO2 could not only extend their photoresponse from the UV to visible light region, but also facilitate efficient charge separation and transfer between SrTiO3−x and TiO2−x. Moreover, their synergistic effects could substantially improve the photoelectrochemical (PEC) performance for water oxidation under visible light irradiation, which is 40 times higher than the PEC capabilities of pristine TiO2 arrays under the same conditions.
