In this work we successfully synthesized cadmium substituted cobalt chromate nanoparticles with the chemical formula Co1-xCdxCr2O4 (x = 0.1, 0.2, 0.3, 0.4, and 0.5) using the solution combustion method. We utilized various characterization techniques including X-ray diffraction (XRD), Fourier transform infrared spectroscopy (FTIR), and scanning electron microscopy (SEM) to examine the structural and morphological changes of the prepared samples. The XRD analysis revealed the formation of a single-phase cubic structure without any impurity peaks, indicating the high purity of the synthesized nanoparticles. Furthermore, we evaluated the humidity sensing capabilities of the prepared nanoparticles across a relative humidity range of 22 to 97 . The sample with the highest cadmium doping level (Cd = 0.5) exhibited the most significant sensing response, with response and recovery times of 55 and 18 s, respectively, and a sensing response of 97 . These results indicate that the synthesized materials are well-suited for humidity sensor applications. our findings demonstrate the successful synthesis of cadmium-doped cobalt chromate nanoparticles with excellent structural characteristics and humidity sensing properties, highlighting their potential for use in humidity sensor technologies. © 2024 Elsevier B.V.
