Published: April 24, 2025

Abstract Formaldehyde is a frequent indoor pollutant that poses risk to human and environmental health suspected be carcinogen. However, achieving high sensitivity selectivity for real‐time applications remains challenging. In this study, room‐temperature operated formaldehyde chemiresistor developed by cerium dioxide/indium oxide (CeO 2 /In O 3 ) nanocomposite exclusive detection. The synthesized using hydrothermal, forming CeO nanospheres grown on nanocubes. This unique structure enhances the sensing capabilities of , allowing it detect in 1–50 ppm range, 0.157 detection limit earned. sensor exhibits an impressive response 175.05 at 50 room temperature shows responsiveness various other substances, instance, methanol, ethanol, aniline, benzene, toluene, acetone, ammonia. Additionally, demonstrated moderate selectivity, sensitivity, stability, speedy response/recovery times, resilience humidity. work presents promising strategy formaldehyde.
