Low-Dimensional Nanostructures Based on Cobalt Oxide (Co3O4) in Chemical-Gas Sensing

Highly sensitive, stable, low production costs, together with easy maintenance and portability, sensors are ever most demanded nowadays for monitoring quantification of hazardous chemicals/gases in the environment. The utilization one dimensional (1D) metal oxide nano structured chemical/gas environmental is vastly investigated because their superior surface to volume ratio, stability, provide information on presence chemical species. Several outstanding attempts have been pursued investigating 1D structures Co3O4 over past decades as an active material analytes detection owing its catalytic effect excellent stability. This article reviews state-of-the-art growth characterization functional sensors. Moreover, fundamental concepts characteristic features, that enhance key performances sensors, discussed. Finally, challenges prospective fabrication
