Narrow-Band HoFeO3 Nanostructure-Based Gas Sensor for n-Propanol Detection

“…10 The introduction of rare-earth elements into perovskite MOS combines the excellent performance of perovskite MOS with the special 4f electronic configuration-related properties of rare-earth elements, and the two synergize to obtain functional materials with more excellent performances. 15 The synergistic effect of these two elements has resulted in functional materials with better performance in the field of catalysis, 16 fluorescent luminescence, 17 refrigeration systems, 17 solar cells, 18 pseudocapacitor, 19 photodiodes, 11 etc. Rare-earth perovskite MOSs have also been widely studied in gas-sensing research.…”

“…At present, perovskite metal oxides (ABO 3 ) have emerged as promising candidates for gas sensors due to their stable structure, easy replacement of A/B sites, and facilely induced abundant structural defects and catalytic active sites .
