Gas Sensor: 1D-Semiconductor Metal Oxide Nanomaterials

Over past years, industrialization has benefited our society greatly in different sectors including energy, communication, transportation and medical. Besides of these developments, surrounding world is on verge of facing the major hazard of environment pollution due to increasing content of toxic gases. In this regard, the detection of a trace of toxic chemical gaseous species is of major concern in research society. Semiconductor oxide materials have widely been used in various areas including gas sensing applications because of their ease of detection both oxidizing and reducing gases, where the numbers of gaseous species adsorbs or desorb on the surface of material mainly counts electrical conductivity change, thereby gives sensing signal. In recent years, many afford have been attempted to upgrade and miniaturization of oxide nanostructures. This study covers depth incite about interface engineering of one-dimensional (1D) normal and hollow oxide nanofibers for gas sensing applications.
