%X In this study, Si was added into FeOOH to prepare Si-FeOOH, and the physical intensity and other properties of Si-FeOOH and FeOOH were compared. The influencing factors of Si-FeOOH-catalyzed ozone on red MX-5B degradation were studied, and the reaction mechanism and the efficiency of decolorization ratio were investigated. The result indicated that, compared with FeOOH, Si-FeOOH had higher physical intensity and was not likely to be crushed in water solution. The iron dissolution was effectively prevented because of the addition of Si, and the effect of Si-FeOOH-catalyzed ozone on red MX-5B degradation was obvious. The decolorization ratio of Si-FeOOH was improved. and the catalytic process followed free radical reaction mechanism. The decolorization ratios increased in response to the increased ozone concentration, whereas the dosage of the catalyst existed an optimum value. Si-FeOOH had a distinct catalytic activity under the neutral condition. The capability of the catalyst was stable, and the catalyst can be recycled and reused.
