Article Description

Cobalt oxide (CoO) nanocatalyst was synthesized by sol-gel method using the protic ionic liquid namely 1-butylimidazolium glycolate as solvent and stabilizer. The obtained CoO nanocatalyst was characterized by powder X-ray diffraction (XRD), Fourier transform infrared, High resolution scanning electron microscopy (HR-SEM), Energy dispersive X-ray (EDX), High resolution transmission electron microscopy (HR-TEM), Selected area electron diffraction, UV–Visible diffuse reflectance spectroscopy, Photoluminescence spectroscopy, Brunauer–Emmett–Teller surface area and Vibrating sample magnetometer (VSM). Powder XRD results showed the well-crystalline cubic structure of synthesized CoO with size of 19.29 nm. Also, the sphere-like morphology of CoO nanocatalyst was confirmed by HR-SEM and HR-TEM images. Furthermore, the synthesized CoO nanocatalyst possessed optical band gap values of 1.75 and 2.46 eV and hence acted as a semiconducting material. In addition, the presence of small hysteresis loop in Magnetic measurement (VSM) confirmed the ferromagnetic nature of CoO nanoparticles. Moreover, the synthesized CoO nanocatalyst found to be used in photo-catalytic degradation of methylene blue and exhibited 94.61% efficiency.
