| Abstract: | The pure silicon mesoporous molecular sieves(HMS) are prepared under the room temperature and the neutral media.The HMS mesoporous molecular sieves are modified by ethanol and aluminum trichloride solution.The modified samples are characterized by XRD,MASNMR,and N2 adsorption-desorption.The results show that the modified samples remain the original mesoporous structural with a smaller specific BET surface area,pore volume and a bigger pore size,pore wall thickness.The ethyl or aluminum atom are grafted to the interior surface or enter the framework of HMS,so the hydrothermal stability of samples has been improved. |
