Abstract


In this study , zirconium oxophosphate mesoporous molecular sieve with new structure was synthesized by hydro-thermal synthesis in the presence of zirconium sulfate and triple quaternary ammonium salt as row material and structure guide agent , respectively .Technology and mechanism of synthesizing this material were studied by XRD,SEM analysis and so on .On the basis of XRD analysis, it was suggested that zirconium oxophosphate mesoporous molecular sieve’s diffraction peaks was obtained at about 2? .The aperture of it ranged from 2.3652 nm to 12.535 nm that was calculated by Bragg equation, which showed that zirconium oxophosphate material was mesoporous material .The specific area of this material was carried out on adsorption—desorption test and adsorption-desorption curve was drew. It showed that this material was mesoporous material, further. Thermo gravimetric analysis indicated that the template was removed effectively by calcining at 500?C and the degree of order of mesopore was increased. SEM of mesoporous material showed that this material was particle with good dispersion.In addition , the diameter of mesoporous material was obtained by changing the mass ratio of triple quaternary ammonium salt Cn-s-m-l/ zirconium sulfate .It was learned that this material had the highest order when the mass ratio of triple quaternary ammonium salt Cn-s-m-l/ zirconium sulfate was 0.625.By changing the amount of phosphoric acid and the treating time of phosphoric acid , the relationship between them and the diameter of mesoporous material was obtained .The aperture of mesoporous material was larger when consistency of phosphoric acid was 0.75mol/L.The larger the time of crystallization was , the higher the degree of order was and the larger the diameter was.At last, the experimental data was disposed by mathematical method, which used Matlab software to fit curves. The mass ratio of the aperture size of mesoporous material and triple quaternary ammonium salt was obtained .We also
