Absence of peaks corresponding to the organic compounds confirms the complete removal of the structure directing agent on calcination at 500°C. Absorption bands at 473 and 620 cm-1 were due to the vibrations of Al–O–Al, while the peak at 742 and 1070 cm-1 can be assigned respectively to the bending vibrations of Al–O and O–H. |

| Absence of peaks corresponding to the organic compounds confirms the complete removal of the structure directing agent on calcination at 500°C. 有机化合物相关峰的缺如证实在500°C 煅烧条件下完全移除了结构导向剂。Absorption bands at 473 and 620 cm-1 were due to the vibrations of Al–O–Al, while the peak at 742 and 1070 cm-1 can be assigned respectively to the bending vibrations of Al–O and O–H.473和620cm-1的吸收带是由于Al-O-Al振动，而742和1070cm-1处的峰则可分别归于Al–O 和 O–H的伸缩振动。 |
