Figure 3

The nitrogen adsorption and desorption isotherms for 2% Fe-HMS, measured at 77.4 K. The inset presents the Horvath-Kawazoe pore size distribution curve for the Fe-HMS catalysts, where is the derivative of the normalized N2 volume adsorbed with respect to the pore size (diameter) of the adsorbent.
