•We synthesized ordered mesoporous In2O3 with mono-, bi- and trimodal pore systems.•We compared melt and incipient wetness impregnation of different silica matrices.•We present a model describing the formation of the different pore systems.•A simple one step synthesis of mesoporous In2O3 was developed.
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.
