“…In particular, nanosized nickel oxides, NiO, are widely used in many technological applications because they exhibit particular catalytic [4,5], anomalous electronic [6,7] and magnetic [8,9] properties. Another important application of NiO is in a battery system [10,11]. Non-stoichiometric nickel oxide is a good P-type semiconductor owing to its defect structure [12] and it is also a potential gas sensor for H 2 [13].…”

Nanosized nickel oxide was synthesized by a simple liquid-phase process to obtain the hydroxide precursor and then calcined to form the oxide. The precursor and the nickel oxide were characterized by X-ray diffraction (XRD), infrared spectroscopy (IR), thermal analysis (TG) and temperature-programmed reduction (TPR). The results indicated that the particle size of nickel oxide was controlled by the calcined temperature (T C ). Mixed phases of nickel oxide and nickel hydroxide were present as the T C was lower than 300°C. Non-stoichiometric nickel oxide (NiO x , x = 1.2) was formed between 250°C and 400°C and a pure nickel oxide was formed as the T C arrived 500°C. The particle size of nickel oxide changed as the calcined temperature was controlled under 250°C, 300°C, 400°C and 500°C, the order was 5.6 nm, 6.5 nm, 11 nm and 17 nm, respectively.

“…In the present model, spatial variation in the microstructure can be imposed on the SnO 2 matrix. Given that a SnO 2 material formed by pulsed laser deposition is being considered, the density was set to 90% theoretical over the 1000 nm depth of the sample, with grain diameters set to 20 nm [6][7][8]. The sensor operating temperature was set at 573 K. The way that a SnO 2 matrix functions as a gas sensor is as follows: In any baseline situation, gases from the neighbouring air diffuse into the porous structure and interact with the ceramic surface.…”

The chemical gas sensor system of CO detection in a SnO 2 matrix was considered. A model was formulated which incorporated the coupled processes of gases diffusing into a porous ceramic and then participating in surface chemical reactions of adsorption, ionization and desorption. Microstructural properties of the sensor matrix were coupled with the diffusion and surface chemistry processes. The consequent surface chemical state served to partition bulk and grain boundary contributions to the n-type material conductance. Conductivity levels determined both with and without the presence of the target gas, CO, allowed sensor response to be determined as a function of film thickness.This simulation represents a modeling advance as it is the first to couple spatial variation of microstructural properties with diffusing gas species and the attendant surface chemistry and electroceramic properties, to predict sensor response as a function of film thickness. This will serve to be a useful design tool for ensuing materials research work towards improved sensor device development.Crown

The available experimental material relating to the patterns of formation and properties of functional nanostructured transition metal oxide (Mo, Co, Mn, Ni, Fe, V) composite materials is reviewed. Advanced coatings are considered those whose formation method are simple and do not require high energy costs, expensive equipment and permit the creation of materials with desired physical and chemical properties in a specified manner. In this review, the priority of oxide composite nanostructured materials technology is given to a transient electrolysis method based on the analysis of a data set that demonstrates its advantages. The results are presented for a number of studies aimed at identifying and analyzing the nature and regularities of processes that take place when obtaining oxide composite nanostructured materials using transient electrolysis methods.
