摘要:
A regular and homogeneous 3D distribution Of In(2)O(3) nanocrystals obtained as a replica of different mesoporous silica-based materials has been tested as a gas sensing material. This procedure based oil the use of hard nanotemplates is shown to give controllable grain size and porosity characteristics. Likewise, the nanostructure characteristics call be targeted according to the used mesoporous nanotemplate, i.e. SBA-15 or KIT-6 in the present work. Fabricated gas sensors show outstanding performances which are discussed and compared with recent improved sensors based oil nanowires or specifically synthesized tiny nanocrystals.
