IR Spectroscopic Study of the Mechanism of Mechanostimulated Transformations of TiO2–MoO3 Heterooxide Composites

IR spectroscopy along with x-ray diffraction and electron microscopy was used to show that the mechanochemical activation of a mixture of Degussa 25 TiO₂ and orthorhombic MoO₃ permits us to grow a disordered MoO₃ shell over titanium dioxide cores. The core–shell structure of the resultant photocatalyst particles facilitates charge separation under actinic irradiation and the accumulation of charge as reduced molybdenum oxide.
