Synthesis of BaSnO₃ Nanofibers for Fast-Response CO₂ Gas Sensing Application

抄録

This study presents an innovative approach to the fabrication of Barium stannate (BaSnO₃) nanofibers for carbon dioxide (CO₂) gas sensing applications. The nanofibers were synthesized using the electrospinning method, enabling the formation of one-dimensional structures with high surface area and enhanced electron mobility. These structural properties significantly improve gas sensing performance, allowing for rapid resistance changes when exposed to CO₂ concentrations ranging from 2,000 ppm to 10,000 ppm. Additionally, the sensor exhibits excellent response and recovery times of 5–7 seconds, confirming its applicability for real-time environmental monitoring. BaSnO₃ nanofibers also offer substantial advantages over conventional detection methods, including superior cost-effectiveness, scalability, and high sensitivity. The study further suggests that dopant incorporation could enhance performance, demonstrating the feasibility of BaSnO₃ nanofibers as a scalable and efficient material for advanced environmental monitoring systems.
