Herein, Ag in situ modified porous LaFeO₃ nanosheets were synthesized by the simple and efficient graphene oxide (GO)-assisted co-precipitation method which was used for sensitive and selective ethanol detection. The Ag modification ratio was studied, and the best performance was obtained with 5% Ag modification. The Ag/LaFeO₃ nanomaterials with high surface areas achieved a sensing response value (R_g/R_a) of 20.9 to 20 ppm ethanol at 180 °C with relatively fast response/recoveNanomaterials (Basel, Switzerland)Ag-Modified Porous Perovskite-Type LaFeO₃ for Efficient Ethanol Detection.PMC91432326207130019ZR1435200, 21ZR1444200, 20490761100, YDZX20213100003002Wang CYuan QWang DChen YYu JYu XfalseAg-Modified Porous Perovskite-Type LaFeO₃ for Efficient Ethanol Detection.Perovskite (ABO₃) nanosheets with a high carrier mobility have been regarded as the best candidates for gas-sensitive materials arising from their exceptional crystal structure and physical-chemical properties that often exhibit good gas reactivity and stability.
