“…Most Reviews have focused on material properties, differentiating the various pure and doped metal oxide materials, [3] and analyzing the effect of, for example, crystal size on sensor sensitivity, [21,29,48] structural stability [26] and selectivity. [25,54] Nanomaterials in general have been identified to improve the performance of sensors, especially regarding sensitivity. [55,56] The size as well as the shape of nanomaterials is tunable, for example, in the form of particles, rods, wires, quantum dots, and core-shell structures, which determine their chemical, optical, magnetic, and electronic properties.…”

Since the development of the first chemoresistive metal oxide based gas sensors, transducers with innovative properties have been prepared by a variety of wet- and dry-deposition methods. Among these, direct assembly of nanostructured films from the gas phase promises simple fabrication and control and with the appropriate synthesis and deposition methods nm to μm thick films, can be prepared. Dense structures are achieved by tuning chemical or vapor deposition methods whereas particulate films are obtained by deposition of airborne, mono- or polydisperse, aggregated or agglomerated nanoparticles. Innovative materials in non-equilibrium or sub-stoichiometric states are captured by rapid cooling during their synthesis. This Review presents some of the most common chemical and vapor-deposition methods for the synthesis of semiconductor metal oxide based detectors for chemical gas sensors. In addition, the synthesis of highly porous films by novel aerosol methods is discussed. A direct comparison of structural and chemical properties with sensing performance is given.

“…A wide range of different metal oxides [223,[228][229][230][231][232][233] and mixed oxides [38,228,229,232,234,235] have been investigated; however, tin oxide is probably the most common system due to the numerous gases it shows a response to. For example, tin oxide has been shown to respond to a wide range of flammable gases, including carbon monoxide, [236][237][238] hydrocarbons, [238][239][240] hydrogen [241,242] and other pollutant gases such as hydrogen sulfide [239,243] and nitrous oxides. [237,244] The use of metal oxide semiconductors as sensor materials is based on the change in resistance that is observed when they are exposed to oxidising or reducing gases.…”

“…For example, tin oxide has been shown to respond to a range of flammable gases, including carbon monoxide [37][38][39], hydrocarbons [39][40][41], hydrogen [42,43], as well as other pollutant gases such as hydrogen sulfide [44,45] and oxides of nitrogen [38,46]. In this role, these metal oxide solid-state gas sensors exploit the inherent properties of these materials, and notably that of semiconductivity.…”

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.
