有序介孔二氧化硅相（例如 KIT-6、SBA-15）用作介孔 In2O3 负复制结构的结构基质。我们详细研究了如何通过系统变化将前体物质 (In(NO3)(3)) 渗透到二氧化硅基质的孔中并随后热转化为 In2O3 的过程来实现产品中单峰、双峰和三峰孔隙系统的受控合成。在封闭反应器中进行熔体浸渍和转化有利于有序介孔氧化铟 (In2O3) 的一步铸造工艺。我们提出了一个基于孔隙填充变化的模型。 (C) 2014 Elsevier Inc. 保留所有权利。
Ordered mesoporous silica phases (e.g. KIT-6, SBA-15) are used as structure matrices for negative replica structures of mesoporous In2O3. We present a detailed study on how the controlled synthesis of mono-, bi- and trimodal pore systems in the products is accomplished by systematic variation of the procedure of infiltrating a precursor species (In(NO3)(3)) into the pores of the silica matrix and subsequent thermal conversion into In2O3. Melt impregnation and conversion in a closed reactor facilitates a one-step casting process for ordered mesoporous indium oxide (In2O3). We present a model based on variation of the pore filling.
