本文採用均勻沉澱法制備納米co _ 3o _ 4粉體材料,研究了制備工藝條件、沉澱反應和前驅體熱分解過程的動力學,主要研究內容及結果如下:以硝酸鈷為原料,尿素為沉澱劑,採用均勻沉澱法制備納米co _ 3o _ 4 ,考察了硝酸鈷濃度、反應物摩爾比、反應溫度和時間、乾燥溫度和時間、煅燒溫度和時間等條件對產物粒徑的影響。Xps measurement results exhibited that no detectable fe2 + existed in the compound of a ~ fe2os doped with sn4 +, which suggest that oxygen anions or cation vacancies not only can compensate the charge balance but also significantly enhance the gas - sensitivity of a - fe2o3 based gas sensors. ( 3 ) conductive type of a - fe2o3 doped with sn4 + is showed in the n - type by hall measurement and gas - sensitivity measurement. the results of measurements and characterizations suggest that the sensitive mechanism of the a - fe2o3 based nano - materials prepared by this work be the surface resistance controlled mode
( 3 )首次進行了霍爾測量,並結合氣敏測試結果,從不同方面證實了摻錫- fe _ 2o _ 3納米半導體的導電類型是n型;綜合粉體的電導率?溫度曲線、元件的電阻?加熱電流特徵曲線、元件在不同氣氛下的電阻特性以及比表面積等測試表徵結果,得出本文所製成的- fe _ 2o _ 3基氣敏元件的氣敏機理特徵屬于表面控制型。She was glad to drive on. it was suddenly hot weather, so hilda was going through switzerland and over the brenner, then through the dolomites down to venice
她高興地離開了巴黎去繼續她們的旅程,天氣突然變得很熱了,所以希爾達決意通過,經布冷納山道,然後從多羅米山地而至威尼斯。In cvd support method, carbon nanotubes were prepared with the supported fe catalyst on the regular mesoporous molecular sieve mcm - 41 by catalytic pyrolysis of c2h2. the author studied systematically the effect of different react conditions on the structure, property and thermal - stability of mcm - 41, and reached an optimum condition of prepared mcm - 41, whose mesoporous diameter was about 2. 9nm, with 0. 12 c16tmabr : 1teos : 0. 24naoh : 66. 7h2o under hydro - thermal condition
Cvd基體法制備碳納米管中,首先探索了不同反應條件對mcm - 41材料結構性能和熱穩定性的影響,優化工藝參數,結果發現水熱條件下反應物的摩爾配比為0 . 12c16tmabr : 1teos : 0 . 24naoh : 66 . 7h2o時制得的mcm - 41材料最適合用來作為催化劑基體材料,其孔徑大小為2 . 9nm左右。分享友人
