Effect of N-doping on the photocatalytic activity of sol-gel TiO2
Nicholas T. Nolan,Damian W. Synnott,Michael K. Seery,Steven J. Hinder,Axel Van Wassenhoven,Suresh C. Pillai +5 more
TL;DR: XPS studies revealed that nitrogen remained within the TiO(2) lattice at higher temperatures, and photocatalytic activity also reduced with increased annealing temperature, resulting in diminished visible light absorption capability.

Synthesis of nano titania particles embedded in mesoporous SBA-15: Characterization and photocatalytic activity
Jun Yang,Jun Zhang,Liwei Zhu,Shaoyuan Chen,Yuanming Zhang,Yu Tang,Yulei Zhu,Yulei Zhu,Yong-Wang Li +8 more
TL;DR: Experimental results indicate that the photocatalytic activity of titania/silica mixed materials depends on the adsorption ability of composite and the photosorption activity of the titania, and there is an optimal ratio of Ti:Si, too high or lowTi:Si ratio will lower the photodegradation ability of the composites.
