Preparation of TiN–TiO2 composite nanoparticles for organic dye adsorption and photocatalysis
Source abstract
Abstract
Abstract TiN, TiO2, and their composite particles have been prepared by a facile urea-glass route involving use of urea as one of the nitrogen sources and titanium chloride as the powder precursor at a relatively low temperature of 800 °C in nitrogen atmosphere. When the molar urea/metal precursor fraction (R) was increased from 1 to 6, the synthesized particles change from predominately TiO2 to TiN, together with a minimum bandgap energy of 2.4 eV at R = 2.5 to 4 for the composites. The presence of TiN appears to impart a pronouncedly enhanced preferential adsorption of methylene blue (MB) dyes in water, due partly to the increased specific surface area. In addition, niobium doping in the composite particles also facilitates the dye adsorption. The MB photodegradation has been found the most pronounced (about 17% after 120 min illumination) when the composites are of the minimum bandgap energy with the absorption edge extending beyond 450 nm.
