a CO conversion of catalysts. b, c In situ XRD patterns of the Fe@Mn@0.05Si (b) and Fe@Mn@0.05Si-c (c) catalysts in the 10%CO/90%N2 atmosphere. d, e, g, h In situ DRIFTS spectra of CO adsorption on the Fe@Mn@0.05Si (d, e) and Fe@Mn@0.05Si-c (g, h) catalysts. The catalysts were exposed to the CO atmosphere at 320 °C for 120 min and then swept in the Ar atmosphere at 320 °C for another 120 min. f, i Normalized intensities of the surface species on the Fe@Mn@0.05Si (f) and Fe@Mn@0.05Si-c (i) catalysts as a function of time.
