ABSTRACT
The application of photocatalysts is to overcome water pollution due to the waste from industrial processing. Photocatalysts using Ag-ZnO composite materials synthesized with Zn(NO3)2 and AgNO3 as Zn and Ag precursors and pineapple peel extract as biostabilizers have been carried out. The percentage of Ag varied, namely 5%, 10% and 15% irradiated using a microwave for 2 minutes with a power of 360 Watt. Sample characterization is detected using Ultraviolet Visible (UV-Vis) spectroscopy, X-Ray Diffraction (XRD) and Scanning Electron Microscopy-Energy Dispersive X-Ray (SEM-EDX) spectroscopy. The peak of UV-Vis absorption occurs at a wavelength of 359 – 368 nm with a band gap energy of 2,96 – 3,00 eV. Based on the X-Ray Diffraction pattern, the crystal structure of the sample is a hexagonal wurtzite structure with a crystallite size of 16,35 – 18,37 nm. SEM particle morphology shows the sample is shaped like a flower with an average particle size of 60,44 – 254,15 nm. The composition of the samples detected by EDX finds element of Zinc, Oxygen, Silver, Carbon, Zirconium, Copper, and Argon. Photocatalyst activity showed that the 10% Ag-ZnO sample is able to degrade the most optimum Methylene Blue Dye seen where the solution is the clearest with a reaction rate constant of 0,0091 min-1. Is summary, Ag-ZnO nanocomposite samples are able to degrade dyes faster than pure ZnO.
