摘要: Abstract Developing efficient and stable hydrogen gas sensors may be of urgent demand for its safety uses. Herein, Pd@N-CeO2 core–shell nanoflatforms (CSNFs) are fabricated utilized this purpose. The resulting CSNFs offer small particle sizes with high Brunauer–Emmett–Teller (BET) surface area porous nanostructures. establish sensing response fast recovery times at a lower optimal working temperature compared to undoped doped CeO2 ones. In addition, it further demonstrates selectivity stability toward among interfering different target gases. betterment is synergistically assigned Pd core, N dopant, BET effects, which decidedly modulate the electrical resistance improve overall performance accordingly. Our finding provides an way design fabricate versatile based on metal@nitrogen doped-semiconductor oxide
