Figure 3 is the isothermal curves of N2 adsorption/desorption and pore size distribution, it shows that the isothermal curve of N2 adsorption/desorption is ¢ô-type ,as the value of P/P0 is between 0.65 and 0.90,it has capillary condensation and H1 hysteresis loop£¬so the catalyst has uniform straight channel. It is also found that the pore size distribution is concentrated and the pore size is 5.92nm. |

The nitrogen adsorption-desorption isotherms and the pore size distribution curve are shown in Fig.3. From Fig.3, it can be seen that the nitrogen adsorption-desorption isotherm (1) of sample is typical ¢ô-type curve and that the ratio of P/P0 is between 0.65 and 0.90. Additionally, the isotherm has capillary condensation phenomenon and H1 hysteresis loop. It indicates that the catalyst has uniform straight channel. The pore size distribution curve (2) also shows that the pore size distribution is concentrated and the pore size is 5.92nm. ¡±±í3ÊÇÎïÐÔÊý¾Ý£¬¡° ÕâÒ»¾äºÃÏñºÍÏÂÎÄÄÚÈÝûʲôÁªÏµÑ½ |
