A facile synthesis of P-modified ZSM-5 zeolite using dual-template system by FAU conversion method |
| 초록 |
ZSM-5 zeolite modified by phosphorus was achieved by employing a binary organic structure directing agents (OSDA) compose of tetrabutylammonium hydroxide and tetrabutylphosphonium hydroxide via FAU interzeolite conversion route at a 170 ℃ oven for 4 days. This approach can easily and exactly control the content of phosphorus in ZSM-5 zeolite structure through changing the ratio of binary OSDAs. The synthesis gel composition was tailored as 1SiO2:0.033Al2O3:0.075Na2O:0.2OSDAs:4.6H2O. The obtained samples were characterized by X-ray diffraction (XRD), N2 adsorption-desorption, scanning electron microscopy & energy dispersive X-ray (SEM-EDX) and solid 27Al, 31P MAS NMR technologies. The hydrothermal stability of P-modified ZSM-5 zeolite was tested in the temperature range of 750 ℃ to 900 ℃ at interval of 50 ℃. Interestingly, the crystalline structure of P-ZSM-5 was significantly preserved after hydrothermal treatment at 900 ℃, which might be attributed to the P species bounded to the surface of ZSM-5 zeolite. |
