- Abstract
A novel catalyst, consisting of hollow silica-coated porous carbon with embedded iron oxide particles (FeO
x @C/SiO2 ), was synthesized by the extended Stöber method. Iron ions were incorporated in a resorcinol-formaldehyde resin in the presence of citric acid to form a template, which was then coated with a silica layer. The iron oxide-embedded porous carbon and hollow silica were simultaneously formed during calcination under N2 atmosphere. Through this process, silica endowed the iron oxide with low crystallinity and small size, resulting in a higher catalytic activity in the heterogeneous Fenton system for the decolorization of a methylene blue (MB) solution within 25 min. Moreover, the sample maintained 78.71% of its catalytic activity after three cycles., Competing Interests: The authors declare that they have no conflict of interest., (This journal is © The Royal Society of Chemistry.)- Published
