Title
Synthesis of uniform anatase TiO2 microspheres with exposed {001} facets: Without HF utilization and Its photocatalytic selectivity
Abstract

•Uniform anatase TiO2 microspheres have been synthesized without using HF.•TiO2 microspheres showed a high percentage of exposed {001} facets.•TiO2 microspheres exhibited higher photocatalytic selectivity.

Uniform anatase TiO2 microspheres with a high percentage of exposed {001} facets have been successfully synthesized by a one-step hydrothermal strategy in the presence of H2O2 and (NH4)2CO3 solution. The as-synthesized anatase TiO2 microspheres with exposed {001} facets exhibited higher photocatalytic selectivity for degradation of methylene blue and methylene orange mixed solution under UV light irradiation at room temperature than anatase TiO2 microspheres without {001} facets exposing and P25 TiO2.
