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

Abstract

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.
