“…The catalytic effect of TiO2 could be improved by changing the doping element of TiO2. Rare earth and transition metal doping can inhibit the growth of particles and crystal transformation and improve the catalytic performance of TiO2 [13,14]. Transition metal elements can exhibit a variety of valence states, and more lattice defects can be formed in the TiO2-doped transition metal ions, which is beneficial to the formation of Ti 3+ oxidation active centers and improve the catalytic effect of TiO2.…”

Nanocomposites of TiO2 co-doped with La and Zr were prepared using the microwave-assisted sol-gel method. The samples were characterized by X-ray diffraction (XRD), scanning electron microscope (SEM), X-ray photoelectron spectroscopy (XPS), energy dispersive spectroscopy (EDS) and specific surface area measurement (BET). The XRD results revealed that all the catalysts showed an anatase phase. It was found that the particle size of La-Zr-TiO2 is much smaller than pure TiO2. Moreover, the denitrification efficiency of La-Zr-TiO2 was 65.77%, which was higher than that of the pure and mono-doped TiO2 in the experiment.
