• Synthesis, characterization and photocatalytic activity of neodymium, nitrogen and neodymium-nitrogen doped $TiO_2$
Kralchevska, R. ...
TiO2 doped with 0.1-10% Nd3+ or 1.8% nitrogen or co-doped with both dopants aswell as Nd2Ti 2O7 are synthesized by a sol-gel. The phase composition, crystal structure, morphology, optical properties ... and binding energies of the doped titania was investigated. The photocatalytic activity was tested for malachite green dye degradation and compared with the results obtained by dopant-free TiO2 synthesized using the same procedure and with the commercial Degussa P25 product. The influence of the dopant type and relative content, temperature of ignition in the course of the synthesis, pH of the reaction medium and the type of the illumination light on the efficiency of the prepared catalysts was determined. A positive effect of Nd- and N-doping on the apparent degradation rate constant under UV irradiation and negative one of Nd-presence at solar illumination is found. Nd-N-codoping has a negative effect on the photocatalytic activity
