Abstracts

EN

TiO2 nanoparticles were synthesized by one-step Sol-gel method. Prepared
nanoparticles were characterized by different characterization (SEM, EDS and
XRD) techniques. The aqueous solution of Methylene Blue (MB) has been
subjected to evaluate the photocatalytic degradation by UV radiation in the
presence of synthesized TiO2 photocatalyst coated reactor. The experiments
were conducted with and without aeration, using different dye concentrations,
and catalyst loading, revealed that the degradation was strongly influenced
by respective experimental parameters. However, maximum MB dye was
removed by the photodegradation process operating with aeration and higher
catalyst dosing.
