Development of high-performance p-type semiconductor gas sensors especially the fast response/recovery speed and high response based on inexpensive non-noble metal oxides without doping or noble metal decoration for the practical applications of gas sensor are highly desirable. In this work, the rapid room-temperature synthesis of innovative and unique parallel copper oxide nanowires assembled microspheres (CuO NMs) with excellent gas sensing property is reported. The morphological characteristics, surface area, porosity, chemical composition a...
