Photocatalytic degradation of acid blue 74 by Co: WO nanoparticles: Kinetics and response surface methodology studies.

Energy-efficient sol-gel synthesis was achieved through the microwave assisted self-combustion route to produce hexagonal Tungsten oxide semiconductor (WO). The photocatalytic activity was enhanced by doping Cobalt (Co) into the crystalline structure of the nanoparticle, which were subsequently sintered at 400 °C for an hour. The structural and morphological properties of the Co-doped WO were revealed using X-ray diffraction (XRD) characterization.
