Abstract:Aluminophosphate mesoporous molecular sieves modified by La was synthesized by structure-director in non-water system using C18NH2 as template.The compose and structure of aluminophosphate mesoporous molecular sieves was characterized by Inductively Coupled Plasma Mass Spectrometry(ICP-MS,infrared spectroscopy(FT-IR),N2 adsorption-desorption,NH3chemisorption(NH3-TPD),XRD and so on.The results show that aluminophosphate mesoporous molecular sieve modified by La has slightly lower surface area,larger acid amount and acid strength compared with the sample unmodified.
Keywords:aluminophosphate molecular sieve structure-director synthesis characterization
