| Abstract: | The perfluorosulfonic acid (PFSA)/SiO2 composite catalysts were prepared by sol-gel method.Differences concerning pore structure analysis of PFSA/SiO2 catalysts were discussed on the basis of nitrogen adsorption.Their surface area and pore size distributions were evaluated by Brunauer-Emmett-Teller (BET) and Barrett-Joyner-Halenda (BJH) methods,respectively.The nitrogen adsorption-desorption isotherms associated with adsorption hysteresis of PFSA/SiO2 catalysts were analyzed in detail.The adsorption isother... |
