中文摘要	Iron-doped porous silica was prepared using poly ethylene glycol (PEG) as the template and tetraethylorthosilicate (TEOS) as silicon precursor. In the novel routine, iron doping and porous material fabrication could be finished in one step. The influence of doping amount of iron on the samples was studied. The low temperature nitrogen adsorption-desorption, SEM, FTIR and XRD methods were employed to analyze the surface area, pore structure and surface groups of the as-made samples. The BET surface area and pore volume of the best sample is higher than 700 m(2).g(-1) and 1 mL.g(-1), respectively. The catalytic performance of the samples upon phenol-decomposition by H(2)O(2) in solution was investigated. The results show that the as-made sample could catalyze the phenol-decomposition reaction by H(2)O(2) in wide pH range (3 similar to 8). The reason might lay in the fact that iron species is stabilized in the framework of porous silica, thus preventing them from hydrolyzing under high pH values.
