Direct in situ synthesis of Fe2O3-codoped N-doped TiO2 nanoparticles with enhanced photocatalytic and photo-electrochemical properties

Herein, we report a facile and simple method for large-scale synthesis of Fe2O3-codoped N-doped TiO2 (Fe2O3/N-TiO2) nanoparticles. The nanoparticles were prepared by calcining a homogeneous mixture of titanium nitride (TiN) and ferric hydroxide colloid (Fe(OH)3 gel) at 500 °C in air and characterized in detail in terms of their morphological, structural, optical, compositional and surface properties using various analytical techniques. Further, the photocatalytic and photo-electrochemical properties of synthesized nanoparticles were also explored and presented in this paper.
