Figure 2 and Figure 3 show the N2 adsorption-desorption isotherms and pore size distribution of MCM-41,MC-1,and MC-2,respectively.According to International Union of Pure and Applied Chemistry(IUPAC)classification[18],MC-1 and MC-2 are the typical type IV isotherms with well-defined H4 hysteresis loops.Yet,MCM-41 is a type IV isotherm with well-defined H2 hysteresis loop,which is characteristic of mesoporous structure(Figure 2).The textural parameters of MCM-41,MC-1,and MC-2 are given in Table 1.The microporous surface areas of MC-1and MC-2 are 950.28 m2/g and 658.53 m2/g,respectively.MCM-41 shows a larger pore volume,while MC-1 possesses the largest microporous volume.
