Abstract
NO2 Sensors In article number 2303631, Wen Zeng, Zaihua Duan, Huiling Tai, and co-workers propose an enhanced gas sensing strategy based on the synergistic effect of electron scattering and space charge transfer, and verify it by designing porous SnO2 nanoparticles assembled from ultra-small grains, achieving unprecedented NO2 gas sensing performance at room temperature. This work provides an innovative approach for developing high-performance and low-power gas sensors.
