“…The larger mesopores of 30.2 nm could be assigned to the cross-link between silica spheres. Remarkably, the hysteresis loop at 0.9 o P/P 0 o1.0 could be attributed to the presence of macropores [11]. These findings are consistent with TEM results.…”

“…Similar formation pathways have been discussed by other groups. 42,61 Differing greatly from the MnO x /3DOMC, the TEM image in Fig. 5d displayed a relatively low dispersion of the MnO x particles with sizes of 20-100 nm in the MnO x /NAC.…”

In this paper, we report a novel nanocomposite of MnO x nanoparticles supported by three-dimensionally ordered macroporous carbon (MnO x /3DOMC) fabricated by means of a simple multi-component infiltration of three-dimensional templates and its use as a catalyst for low-temperature selective catalytic reduction (SCR) of NO x with NH 3 . Several techniques, including scanning electron microscopy, X-ray diffraction, N 2 -sorption, transmission electron microscopy, X-ray photoelectron spectroscopy, NH 3 temperature-programmed desorption, and H 2 temperature-programmed reduction, are employed to characterize the MnO x /3DOMC nanocomposite. The results demonstrate that MnO x /3DOMC possesses a highly ordered macroporous structure with hierarchical mesopores in the walls of the macroporous skeleton. MnO x nanoparticles of 2-4 nm are observed to be highly dispersed on the 3DOM carbon scaffold. Compared with the MnO x /NAC and MnO x /TiO 2 catalysts prepared by a conventional impregnation method, the MnO x /3DOMC catalyst exhibits better low-temperature NH 3 -SCR activity, stability, and water vapor and/or SO 2 resistance ability. Such material represents a promising exploratory direction for enhancing the catalytic performance of metal oxide-based NH 3 -SCR catalysts.
