/ZnO heterojunction hybrid nanofibers are successfully synthesized by electrospinning.The gas-sensing characteristics of the heterojunction nanofiber gas sensor to ammonia in different environments are studied and analyzed through experiments.The results show that the sensor responds quickly to ammonia with a concentration of 300×10
