Photocatalytic degradation of methyl orange in the presence of aluminium-doped zinc oxide / Nur Aliyah Alwani Mohd Nazam

AI-doped ZnO (AZO) photocatalysts with different AI concentrations (1-10 mol %) were prepared through sol-gel method and followed by drying process at 300°C for one hour. The obtained samples were characterized by X-Ray Diffraction (XRD), Field Emmision Scanning Electron Microscope (FESEM) combin...
