Abstract

The manuscript covers Vanadium Pentoxide Gas Sensors: Elemental Doping Strategies and Sensing Performance Impact. In this paper, we discuss elemental doping ways to improve gas sensing performance in V₂O₅ sensors. The sensing characteristics of V₂O₅ are influenced by dopants such as transition metals, rare earth elements, and non-metals. We investigate the processes behind doping-induced enhancements in sensitivity, selectivity, response time, and stability. Additionally, we explore elemental doping issues and constraints, such as precise process control, crystal structural alterations, and dopant concentration implications on sensing characteristics. This study demonstrates the possibility of elemental doping for modifying gas detecting capabilities in V₂O₅ sensors for various applications.
