Metal oxides for solid-state gas sensors: What determines our choice?
نویسنده
چکیده
The analysis of various parameters of metal oxides and the search of criteria, which could be used during material selection for solid-state gas sensor pplications, were the main objectives of this review. For these purposes the correlation between electro-physical (band gap, electroconductivity, ype of conductivity, oxygen diffusion), thermodynamic, surface, electronic, structural properties, catalytic activity and gas-sensing characteristics f metal oxides designed for solid-state sensors was established. It has been discussed the role of metal oxide manufacturability, chemical activity, nd parameter’s stability in sensing material choice as well. 2007 Elsevier B.V. All rights reserved.

High selectivity, enhanced sensitivity, short response times and long shelf-life are much sought-after features in solid-state chemical sensors for the detection and metering of gas(es) of interest. Because the sensing mechanism of semiconducting oxides is invariably surface dominated, benign microscopic features are desirable to realize a useful sensing material. In principle, such morphologic...

Two organometallic compounds containing zinc and manganese in different ratios are used as single-source precursors for the preparation of various new, bimetallic oxide materials with nanoscaled dimensions. It is shown that the materials synthesis can be performed in the solid-state, the liquid-phase, and even in the gas-phase. The molecular composition of the precursors determines the composit...
