Abstract (EN): Nanoporous silica materials of regular porosity (of SBA-15 type) doped with magnetic iron oxide nanoparticles were prepared by two routes that differ essentially in the pH of the reaction medium and calcination step. Both routes produced magnetic SBA-15 materials with regular porosity and containing different loadings of iron oxide particles. The increase of the amount of iron oxide incorporated in SBA-15 was directly related with the increase of the pH during the material synthesis but the magnetic properties also showed a dependence on the type of calcination used. Two of the prepared materials showed relevant results for the catalytic degradation of acetaminophen, a pharmaceutical emerging pollutant. In the present work mild reaction conditions were used, that is, reaction conditions that do not involve imposition of low pH values, a specific radiation source nor high-pressure autoclave.
