Book excerpt: Sensors are the devices, which are composed of an active sensing material with a signal "transducer". The role of these two important components in sensors is to transmit the signal without any amplification from a selective compound or from a change in a reaction. These devices produce any one of the signals as electrical, thermal or optical output signals which could be converted in to digital signals for further processing. One of the ways of classifying sensors is done based on these output signals. Among these, electrochemical sensors have more advantage over the others because; in these, the electrodes can sense the materials which are present within the host without doing any damage to the host system. On the other hand, sensors can be broadly classified in to two categories as chemical sensors and biosensors. The biosensors can be defined in terms of sensing aspects, where these sensors can sense biochemical compounds such as biological proteins, nucleotides and even tissues [1-4]. Within these sensors, the active sensing material on the electrode should act as a catalyst and catalyze the reaction of the biochemical chemical compounds to obtain the output signals [1,5, 6]. The combination of these two different ways of classifications has given rise to a new type of sensors which are called electrochemical biosensors, where the electrochemical methods are applied for the construction and working of a biosensor [ l, 7-9]. The selection and development of an active material is a challenge. The active sensing materials may be of any kind as whichever acts as a catalyst for sensing a particular analyte or a set of analytes. The recent development in the nanotechnology has paved the way for large number of new materials and devices of desirable properties which have useful functions for numerous electrochemical sensor and biosensor applications [l, 10-14]. Basically by creating nanostructure, it is possible to control the fundamental properties of materials even without changing their chemical composition. In this way the attractive world of low dimensional systems, together with the current tendencies on the fabrication of functional nanostructured arrays could play a key role in the new trends of nanotechnology [ 1, 15-17]. Further, the nanostructures can be used for both efficient transport of electrons and optical excitation, and these two factors make.

This book was released on 2021-04-21 with total page 374 pages. Available in PDF, EPUB and Kindle. Book excerpt: Metal oxide nanomaterials exhibit interesting electrical and photochemical properties because of their size, stability, and high surface area that render them as great choices in fabricating alternative electrode materials for electrochemical energy storage and sensor applications. The hybridization of metal oxides with other materials lead to the improvement in electrical conductivity, stability, and electron transfer kinetics during the electrocatalytic reactions. These key factors result in greater sensitivity of the sensor materials towards the analyte molecules. This book reviews the electrochemical determination of a variety of toxic chemical contaminants using metal oxide-based nanocomposite materials. Ultrasensitive and selective detection of toxic chemical contaminants is important and demanding, especially for monitoring and controlling environmental pollution. In recent years, metal oxide-based nanocomposite materials have shown high potential in the electrochemical detection of heavy metals, inorganic anions, phenolic compounds, pesticides, and chemical warfare reagents. Metal Oxides in Nanocomposite-Based Electrochemical Sensors for Toxic Chemicals comprehensively reviews this topic. In addition to the instrumental simplicity, the electrochemical methods show the improved sensor performance through the synergetic effect of metal oxide and other electroactive nanomaterial present in the nanocomposite.

Book excerpt: This thesis reported synthesis of TiO2 nanostructures and Fe2O3 nanostructures and studied on self-assembling process. The morphologies, compositions, and physicochemical properties of the prepared samples were characterized by TEM, FESEM, XRD, FTIR, UV, and SQUID etc. Nanoparticles of transition metal oxides own their special function to become an interesting hot research topic in the recent decades.

Titanium dioxide nanoparticles can be applied in photocatalysts, UV protectors and dye sensitive solar cell etc. Their wide industrial applications for advanced technology development motivate scientists to develop simple, economical and novel synthetic methods, and explore their applications, so that the commercialization of the production of the nanomaterials becomes feasible. The objective of this project is to develop an effective, simple and economical technical route for synthesis of nanosized iron oxide and titanium oxide particles/rods/films. The approach and the progress are outlined as follows. Based on extensive literature reading on the project related area, a novel self-assembling technical route for iron oxide nanostructure and architecture was proposed which has been confirmed to be effective. Detailed experimental investigation on the synthesis of nanoparticles/rods, and instrumental characterization of the particle size, structure, and crystallites, etc. via TEM, FESEM, XRD, FTIR, UV, SQUID are conducted. Uniform nanorods of hematite iron oxide and titanium oxide nanospheres, and anatase TiO2 thin film with micropores have been successfully achieved. Some preliminary exploration for applications of the synthesized nanomaterials has also been carried out. Firstly, a novel assembled scheme of iron oxide nanostructure and architecture by selfassembling process was investigated. The sol-gel technical route was employed to synthesize nearly uniform nanorods of hematite particles. Morphologies and physicochemical properties of iron oxide nanostructure were characterized by analytical instrument. Secondly, titanium oxide nanospheres were synthesized via a hydrothermal process using titanium isopropoxide as the precursor. Titanium oxide nanospheres with inner nanospace andhighly organized crystallites in the shell structure and surface regions were synthesized. It demonstrated that the technical route developed in this work has a high versatility for structural engineering of various targeted morphological products. Thirdly, a simple process of preparing anatase TiO2 thin film with micropores was pursued. The synthesized nano thin film with micropores was used for the material of dye-sensitive solar cell; and effective electron transfer of titanium oxide electrode was confirmed by electrochemical voltammetry. Preparation of the titanium oxide electrode and its electrochemical analysis was studied. The application of the titanium oxide of microporous thin film material as a promoter for electrochemistry voltammetry measuring system was explored in this thesis. In conclusion, the iron oxide nanorods with superparamagnetic property were successfully synthesized by a simple method with low cost materials. Titanium oxide hollow nanospheres were achieved by the assistance of copolymer template. Titanium oxide thin film with microporous structure with significantly high efficiency in electron transfer was realized. Further researches on the synthesis of hybrid iron oxide and titanium oxide nanoparticles, their crystal growth architecture and mechanism, as well as exploration of their applications are recommended.
