Perovskite semiconductor materials attracted tremendous interest in heterogeneous photocatalysis. However, most of these semiconductors have limited charge mobility and poor charge separation. Using a flux-assisted technique, we synthesized high symmetry anisotropic facets (18-facet SrCoTaO) double perovskite oxide semiconductor. Surface doping of sulfur (S) and carbon (C) into the lattice of a particulate novel SrCoTaO induced microstrain to enhance the photocatalytic conversion of CO by boosting charge density to tune charge-carrier mobility. The S and C incorporation boosted the photocatalytic CO reduction more than eleven orders of magnitude higher than pristine SrCoTaO under visible light irradiation. Such efficient photocatalytic CO reduction is attributed to the synergistic effect of tuning the carriers mobility and spatial charge separation via chemical and electronic engineering of the particulate (S, C)-codoped SrCoTaO. The concept of fabrication of spatial charge separation and engineering electron mobility will explore a new avenue to design an efficient photocatalytic system for the conversion of solar energy to solar fuels.
