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.
