Abstract	Researchers studied the catalytic reaction mechanism of surface cobalt-loaded red mud (RM) using the reaction kinetics analysis and catalyst surface property characterization. They employed multiple characterization methods to examine the variation of surface texture and chemical properties of the catalyst after surface cobalt loading. They then identified the contributions of molecular ozone, hydroxyl radicals, and surface adsorption for bezafibrate (BZF) degradation by Co/RM by the reaction kinetic analysis using the tertiary butanol used as an organic quencher, confirming that surface cobalt loading promoted the role of the hydroxyl radical reaction.
