Abstract

We introduce a high surface area sensor composed of Co₃O₄ nanoparticles (NPs) embedded within porous ZnO nanofibers (NFs), exhibiting a notable response to acetone. Initially, we synthesized polyvinylpyrrolidone (PVP) NFs containing zinc and cobalt salts via a simple electrospinning method. Subsequently, the calcination of the PVP NFs resulted in the formation of Co₃O₄ NPs embedded within the porous ZnO NFs. The heterostructure material demonstrated a significant response to 100 ppm acetone detection, with a ratio of electrical resistance in air (R_a) to that in the presence of gas (R_g) reaching 111 at its optimal operating temperature of 275 °C. Furthermore, it exhibited stable performance under high relative humidity conditions.

期刊介绍： While ceramics have traditionally been admired for their mechanical, chemical and thermal stability, their unique electrical, optical and magnetic properties have become of increasing importance in many key technologies including communications, energy conversion and storage, electronics and automation. Electroceramics benefit greatly from their versatility in properties including: -insulating to metallic and fast ion conductivity -piezo-, ferro-, and pyro-electricity -electro- and nonlinear optical properties -feromagnetism. When combined with thermal, mechanical, and chemical stability, these properties often render them the materials of choice. The Journal of Electroceramics is dedicated to providing a forum of discussion cutting across issues in electrical, optical, and magnetic ceramics. Driven by the need for miniaturization, cost, and enhanced functionality, the field of electroceramics is growing rapidly in many new directions. The Journal encourages discussions of resultant trends concerning silicon-electroceramic integration, nanotechnology, ceramic-polymer composites, grain boundary and defect engineering, etc.
