Hierarchical and hollow oxide nanostructures are very promising gas sensor materials due
to their high surface area and well-aligned nanoporous structures with a less agglomerated …

In this review the structural and physical–chemical properties of nanoscaled metal oxide
films (SnO2 and In2O3), aimed for solid state chemical sensors were analyzed. It has been …

Catalytic conversion of CO2 to liquid fuels or valuable chemicals is an attractive alternative
to geological sequestration. In the present study, we applied density functional theory slab …

This review paper discusses the influence of morphology and crystallographic structure on
gas-sensing characteristics of metal oxide conductometric-type sensors. The effects of …

When the sizes of materials are reduced in one or more dimensions their physical and
chemical properties can change dramatically. These changes affect their electromagnetic …

Mesoporous In2O3 nanofibers with a high surface area were synthesized by calcining
electrospun polyvinyl alcohol (PVA)/indium acetate composite fibers. A PVA solution and …

Based on the experimental results, obtained by studying both structural and gas-sensing
properties of the SnO2 and In2O3 films deposited by the spray pyrolysis method, we …

The structural, electrical and optical properties of RF sputtered In 2 O 3: Sn (ITO) thin films
and the effect of post-deposition annealing have been studied. The thickness ranges from …

The influence of the thickness of SnO2 films deposited by a spray pyrolysis method on the
operating characteristics of gas sensors is analyzed in this paper. It outlines how the …

There is currently a high demand for highly-sensitive semiconductor gas sensors operating
at low temperature, which would be compatible with semiconductor technology and could be …
