Abstract

For the first time, InTaO4 photocatalysts with different morphologies and structures were facilely prepared using a versatile sol precursor. SEM, TEM and HRTEM were used to characterize their structures and morphologies. The as-synthesized materials exhibit different physicochemical properties. Compared to InTaO4 nanoparticles and SiO2@InTaO4 core-shell nanospheres, InTaO4 nanofibers have higher light absorption ability, larger specific surface area, and better photocatalytic activity for hydrogen evolution. We proposed mechanisms for the formation and photocatalytic activity of the three catalysts. The present work not only provides a new approach for the synthesis of tantalates that are different in morphology and structure but also offers new insights into the controllable preparation of photocatalysts through a versatile precursor for environmental and energy applications.
