Ultrasensitive Sensors Based on PdO@SrFe₂O₄ Nanosphere-Modified Fibers for Real-Time Monitoring of Ethanol Gas

Spinel ferrites have attracted great interest in the research of sensing materials due to their excellent catalytic activity and flexible and tunable physical properties. Here, we report an environmentally friendly technique using an electrospinning system, followed by a hydrothermal method, to fabricate a highly sensitive ethanol sensor based on PdO nanosphere-modified SrFe2O4 fibers for real-time monitoring. From the evaluation of SEM, TEM,...
