摘要

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.
