Highly ordered magnetic mesoporous silicas for effective elimination of carbon monoxide

► MS based heterogeneous catalyst with Fe nanoparticles were demonstrated for CO elimination. ► Highly Fe nanoparticle embedded MS catalyst prepared by hydrogen reduction process. ► Systematic characterization was achieved by XRD, XPS, BET, and HR-TEM analyses. ► More than 90% of the CO was eliminated at RT during 80 min with 0.5 g of catalyst.
