FT-IR spectra for powder and extrudate samples have been shown in Fig.5 in range of 400-1400 cm-1 wave number. Structural vibrations near the bands: 450, 540, 860, 1120 and 1225 cm-1 that are the ZSM-5 Zeolite specification, for both powder shape and extrudate is visible in Fig.5. 540 cm-1 band is related to stretching vibration of double five membered rings (D5R) in MFI network that are completely alternative which are connected along a, b, c axis or at the intersection of channels. Meanwhile around the 450cm-1 band, appeared peak shows bending vibration of T.O connection related to TO4 tetrahedral. 800 cm-1 and 1120 cm-1 bands are relevant to outside stretching symmetric vibrations and inside stretching asymmetric vibrations respectively. |

粉末和擠出樣本的FT-IR光譜如圖5所示,波數(shù)在 400-1400 cm-1之間。 圖5中,粉末和擠出物的結(jié)構(gòu)性振動(dòng)在屬于ZSM-5沸石規(guī)格的450, 540, 860, 1120 和 1225 cm-1波段附近是可見的。 在MFI網(wǎng)絡(luò)的雙五圓環(huán) (D5R)結(jié)構(gòu)中,540 cm-1波段和彈性振動(dòng)相關(guān)。在此結(jié)構(gòu)中,a、b、c軸之間相互連接,或者在通道的交叉處,因此是可相互替代的。另外,在 450cm-1附近, 出現(xiàn)的峰值表明,T.O連接的彎曲振動(dòng)與TO4 四面體有關(guān)。 800 cm-1 和1120 cm-1波段分別與外部對(duì)稱性彈性振動(dòng)和內(nèi)部非對(duì)稱性彈性振動(dòng)相關(guān)。 外行人純粹手工翻譯。僅供參考。 |
