英文摘要	A highly crystallized mesoporous Ni3N with core-shell structure was prepared from a green and template free method. The Ni3N was characterized by using powder X-ray diffraction (PXRD), scanning electron microscopy (SEM), Brunauer-Emmett-Teller (BET) surface area analysis, and the measured Ni3N has a specific surface area of 85.89 m(2) g(-1) and a narrow pore size distribution centered at 5 nm. After air oxidization, the Ni3N/NiO composite was further evaluated for NO2 gas sensing at room temperature, and the Ni3N/NiO-based sensor exhibited excellent selectivity for NO2 gas. A good linear relationship between the sensor response and the NO2 gas concentrations was observed. The enhanced NO2 sensing performance can be attributed to the highly crystallized mesoporous and core-shell structures of the synthesized Ni3N/NiO.
