Abstract

It is an important task for modifying heterogeneous Fenton catalysts to effectively degrade organic pollutants in water. Most studies have modified heterogeneous Fenton catalysts through addition of other metal active species. Here, a series of Si-Fe/γ-Al2O3 (x, x = Si/Fe mass ratio per gram of support) catalysts were prepared via wet impregnation method, and the characterization results show that the addition of trace Si (x < 0.10) facilitated the dispersion of Fe species, thereby leading to an increase in the specific surface area, average pore size and pore volume of the catalysts. At the same time, trace Si addition can effectively improve the acid-base properties of the catalyst surface. All these changes may be beneficial to the catalytic degradation of the phenol simulated wastewater.
