英文摘要: Abstract(#br)Herein, we present a high-performance NO 2 sensor operating at room temperature based on ZnO nanorods functionalized by nonplasmonic Pd nanoparticles. Optoelectronic measurements revealed that the ZnO/Pd hybrids exhibited high photocurrent with ultrafast rise/decay rates under visible light with optimal wavelength (λ = 475 nm), which was related to the photoexcited nonplasmonic electron injection from Pd nanoparticles to ZnO nanorods. Characterization of the visible-light-activated gas sensing performance is pursued at ppb-level of NO 2 resulting in high responses, fast response/recovery rate, low detection limit as well as full reversibility. The enhanced optoelectronic NO 2 sensing performance of the ZnO/Pd hybrid was attributed to the photoexcited nonplasmonic electrons....
