Abstract
Molybdenum trioxide is a versatile material widely studied for its unique structural, electronic, and optical properties, making it suitable for applications in catalysis, photocatalysis, energy storage, and environmental remediation. In this study, the structural and functional properties of undoped and Co-doped MoO3 on SiO2 were systematically investigated through XRD, FESEM, TEM, UV-Vis, FTIR, EDS, and dye degradation experiments. The XRD analysis revealed the crystalline structure and lattice distortions induced by Co doping, while FESEM and TEM demonstrated the morphological evolution, including agglomeration and increased surface roughness. Optical studies using UV-Vis spectroscopy showed a bandgap narrowing upon doping, enhancing photocatalytic activity. The FTIR spectra highlighted shifts in vibrational modes, confirming structural modifications due to doping. The EDS analysis confirmed the successful incorporation of cobalt into the MoO3 matrix. The photocatalytic efficiency of 6% Co-doped MoO3 was evaluated using Isolan Black dye, with results showing significant degradation within 60 min. Based on the findings, the Co-doped MoO3 on SiO2 can be claimed as an efficient material for environmental and catalytic applications
