Metal oxide gas sensors have long faced the challenge of low response and poor selectivity, especially at room temperature (RT). Herein, a synergistic effect electron scattering space charge transfer is proposed to comprehensively improve sensing performance n-type metal oxides toward oxidizing NO2 (electron acceptor) RT. To this end, porous SnO2 nanoparticles (NPs) assembled from grains about 4 nm with rich oxygen vacancies are developed through an acetylacetone-assisted solvent evaporation approach combined precise N2 air calcinations. The results show that as-fabricated NPs sensor exhibits unprecedented -sensing performance, including outstanding (Rg /Ra = 772.33 @ 5 ppm), fast recovery (<2 s), extremely detection limit (10 ppb), exceptional selectivity (response ratio >30) Theoretical calculation experimental tests confirm excellent mainly attributed unique transfer.
