Abstract

A new mechanically stable TiO2-P25@n-TiO2 nanocoating was prepared after grafting of size-selected titanium-oxo-alkoxy particles on P25-TiO2 nanoparticles surface and their immobilization on a glass substrate followed by a thermal treatment. The 5-nm oxo-TiO2 particles were prepared in a sol-gel reactor with rapid reagents micromixing. The photocatalyst with 65% TiO2-P25 loading shows the highest activity towards ethylene degradation in a continuous-flow fixed-bed reactor. This material has a higher activity compared to that prepared by a conventional sol-gel method with strongly polydispersed titanium-oxo-alkoxy nanoparticles and clusters. The reaction conditions were explicitly analyzed along the reactor as a function of the ethylene concentration in framework of a kinetic model, which shows interplay between zero and first order processes
