Porous γ-Fe2O3 nanoparticle decorated with atomically dispersed platinum: Study on atomic site structural change and gas sensor activity evolution

Qiheng Li et al.

Summary: Decorating semi-conducting metal oxide with noble metal single atom sites has been proven to be an effective way to improve the sensitivity and selectivity of gas sensors. The atomically dispersed platinum on one-dimensional arranged porous gamma-Fe2O3 nanoparticle composites showed high response and good selectivity to ethanol gas, indicating the potential for ISAS-enhanced gas sensors for other volatile organic compounds (VOCs). This work highlights the importance of noble metal single atom sites in enhancing the performance of metal oxide gas sensors.
