چکیده
|
In this study,we perform a catalytic decomposition of organic dye over fe2o3-ceo2-tio2-γ-al2o3 catalyst in the presence of molecular oxygen and chlorate ions. the results showed that organic dye acts as a sensitizer during this process. the mechanism of the allover process is hypothesized. several techniques were employed for the characterization of the catalyst,including xrd,sem,edax,and thermal analysis and catalytic activity. the analysis showed that iron is the main active centers,and we have two types of active centers in this process: surface iron and dissolved iron in titanium dioxide. the dissolved iron was found to be the most active center; however,after fe/ti = 2.76,a synergism was observed to be occurring between the two active centers. © 2016 samia a. kosa et al.
