Abstract

Photocatalysis due to degrading the dyes pollution without give a negative impact on the environment is really interesting. To study the photodegradation, the NiO/nGO catalysts with the ratio of NiO to nGO 0.125/1, 0.250/1 and 0.5/1, were prepared respectively using the gel sol method. Then, the characterization is done such as the X-Ray Diffraction (XRD) method showed that all ratio catalysts had two crystalline phases, n-GO and NiO. The crystalline sizes are 5.45, 8.46, and 17.56 nm, respectively. Infrared spectra of the samples showed the formation of Ni-O and C-OH functional groups. The SE micrograph indicated that the catalysts contained Ni, O, C, and H elements and had agglomeration. The band-gap energy of the catalysts is 1.52, 1.50, and 1.63 eV as a follow as the ratio. The experiment proved that all catalyst was active and successfully reduced the RGY by 90 and 80% at the exposure time of 120 minutes, using a visible lamp source and that of 41% using sunlight.
