Specific Sn–O–Fe Active Sites from Atomically Sn-Doping Porous Fe2O3 for Ultrasensitive NO2 Detection
Highlights The heteroatom atomically doping strategy was reported to construct highly efficient sites on metal oxides for the detection of low-concentration gas. The atomically dispersed Sn atoms were intentionally incorporated into the Fe2O3 lattice during the oxidative annealing of Fe-based metal...

| description | Highlights The heteroatom atomically doping strategy was reported to construct highly efficient sites on metal oxides for the detection of low-concentration gas. The atomically dispersed Sn atoms were intentionally incorporated into the Fe2O3 lattice during the oxidative annealing of Fe-based metal organic framework, leading to specific Sn–O–Fe sites, porous structures, and abundant oxygen vacancies. The optimized Sn-Fe2O3 exhibited exceptional sensing performance for NO2 detection: ultra-high sensitivity (Rg/Ra=2646.6 to 1 ppm NO2), ultra-low limit of detection (10 ppb), and high selectivity. |
