Excellent ethanol sensor based on LaFeO3 modified with gold nanoparticles

Porous LaFeO3 perovskite catalysts synthesized by different methods and their high activities for CO oxidation

“…In addition, the preparation raw materials for the preparation of LaFeO 3 catalysts have less environmental pollution and are cheaper and easier to obtain. LaFeO 3 is widely used in various fields, including the production of solid oxide fuel cells, 10 sensors, 11 oxygen permeable membranes, 12 and environmental catalysts. 13,14 Therefore, the study of LaFeO 3 perovskite catalysts is of great significance in terms of economy and environmental protection.…”

Enhanced Gas Sensitivity of Au-Decorated Flowery WSe2 Nanostructures

“…Peng et al [ 16 ] decorated a ZnO nanostructure with 6% Au NPs and found that the composite sensor has about a nine-fold enhancement in its gas response to 100 ppm acetone at 280 °C compared to pristine ZnO. Li et al [ 17 ] reported that the sensitivity of the Au@LaFeO 3 gas sensor to 100 ppm ethanol is 27 times higher than that of the pure LaFeO 3 sensor at an optimal operating temperature. In our previous work, we also found that the response of the Au@CuO sensor is seven times higher than that of the pure CuO sensor exposed to 1000 ppm ethanol [ 18 ].…”
