摘要: 利用XRD,XPS,TPR等技术对Ga2O3/HZSM-5催化剂进行表征,结果表明,催化剂中镓组分以聚集态和分散态的形式存在,其中聚集态中α-Ga2O3在一定条件下可转化为β-Ga2O3;分散态又可分为游离Ga2O3和与HZSM-5产生相互作用的镓组分,催化剂预处理条件及反应一再生过程对镓的分布及状态有较大影响.关键词:...
Using in situ time-resolved X-ray diffraction (XRD), we have monitored the formation of wurtzite (Ga1−xZnx)(N1−xOx) compounds during the solid-state reaction of NH3 with Ga2O3/ZnO mixtures or a ZnGa2O4 spinel. The ZnGa2O4 spinel was found to be a key intermediate in the ...

In this context, Fridell and co-workers have investigated the addition of metal oxide additives including WO3, MoO3, V2O5and Ga2O3on the deactivation of Pt/Ba/ Al2O3[13]. Although MoO3addition enhanced NO oxidation and showed the lowest SO2 oxidation activity, the storage capacity of the ...
No reaction with Ga2O3 occurred where the GeO2 was replaced by SiO2. Thermal treatment of gel precursors produces intermediate amorphous phases in which the Al is in typical sites with a 27Al MAS NMR resonance at 33ppm, in addition to tetrahedral and octahedral sites. Crystallization of the ...
Solid solubility limits of Al2O3 and Ga2O3 in Gd2O3-doped CeO2 The article presents a study that determines the solid solubility limits of Al2O3 and Ga2O3 in Gd2O3- doped CeO2by X-ray diffractometry and scanning electr... Joo-Sin Lee,Kwang-Hoon Choi,Bong-Ki Ryu,... - Journal ...
