“…The response of doped (10 % CuO and 10 % CdO) nanocrystalline thick films of barium titanate were studied with respect to CO, LPG, H 2 S and H 2 . [279] It was found that the selectivity of the sensor was improved for LPG over the other gases at 250°C. However, the addition of 0.3 wt% Pd resulted in an even greater selectivity to LPG at a lower temperature of 225°C.…”

“…For example, nanocrystalline thick films of both barium titanate [279] and cobalt titanate [280] have been investigated as possible sensor materials. Doped nanocrystalline CoTiO 3 thick films (Gd, Ho, K, La, Li, Na, Pb, Sb and Sm doped at 2 at%) exhibit p-type semiconductivity and a response to both ethanol and propylene.…”

“…The use of more complex metal oxides has also been investigated, with nanocrystalline thick films of both barium titanate [96] and cobalt titanate [97] having been considered as possible sensor materials. When the response of such barium titanate films doped with 10% CuO and 10% CdO was studied with respect to CO, LPG, H 2 S, and H 2 [96], sensor selectivity was improved for LPG over the other gases at 250 C. However, the addition of 0.3 wt% Pd resulted in an even greater selectivity to LPG at a lower temperature, of 225 C.…”

The aim of this chapter is to review the current state of knowledge in ionic materials with crystallite dimensions less than 100 nm, systems which sometimes are referred to as nanoionics. The chapter will detail the preparation, characterization and the important applications of these materials, especially in sensors, solid-state batteries, and fuel cells. Particular focus will be placed on ionic transport in these materials, as this is a topic of considerable contemporary interest, and where conflicting reports exist of enhanced diffusion in nanocrystals. IntroductionNanomaterials are systems that contain particles with one dimension in the nanometer regime. The past decade has witnessed a growing intense interest from biologists, chemists, physicists, and engineers in the application of these materialsthe so-called nanotechnology, which is sometimes referred to as the next industrial revolution [1]. The reasons for such interest are the unusual properties and potential technological applications that are exhibited by these materials when compared to their bulk counterparts [2][3][4][5][6][7][8][9][10]. In this chapter, attention will be focused on rather simple ionic solids, where the interatomic attractions are predominantly coulombic forces, and the dimensions are predominantly <100 nm. Such systems have been termed nanoionics [11,12].There are three dominant reasons for the study of these particular systems:. The simplicity of the interatomic forces means that some of the generic features and problems of nanomaterials should be tractable to theoretical and/or computer modeling approaches for these particular systems. . Many relatively simple ionic compounds, such as binary halides and oxides, in their bulk form have important technological applications as electrolytes, catalysts, Solid State Electrochemistry I: Fundamentals, Materials and their Applications.

“…Over the last decade, considerable attention has been focused on the synthesis and characterization of nanostructured metal oxides for the fabrication of low cost, selective and low temperature operative gas sensors [1].Nanostructured metal oxides such asundoped SnO 2 [2], SnO 2 doped with nobel metals [3], CdO [4], WO 3 [5], Al doped ZnO [6] and BaTiO 3 [7] have been investigated in the past decades as liquid petroleum gas (LPG) sensing materials because of their low cost, ease of synthesis, versatility in detecting a wide range of toxic/flammable gases and stability in harsh environments. In particular, ZnO is extensively used in the fabrication of gas sensors for detecting various toxic and flammable gases.…”

ZnO nanorods (diameters∼25 nmand lengths∼145-150 nm) were synthesized by using a simple solochemical method and their LPG sensing properties were investigated. The ZnO nanorods exhibited outstanding gas sensingcharacteristics such as, higher gas response (∼502 to 50ppm LPG at 300 •C), extremely rapid response(∼6-7 s), fast recovery (∼6-7 s), excellent reproducibility, good sensing selectivity and relatively lower operating temperature(∼300•C). The experimental results clearly demonstrate the potentialof using the ZnO nanorods as sensing material in the fabrication of LPG sensors.
