PHOTOCATALYST COATING OF MNO-FE2O3PS FROM NATURAL MATERIALS

Abstract

The present invention relates to an Photocatalyst coating of MnO-Fe₂O₃/PS from natural materials. Photocatalyst is a method for reducing liquid pollutant materials using ultraviolet (UV) light to produce oxidizing and reducing species on the surface of the catalyst. The catalyst used is MnO-Fe₂O₃/PS. The tools used are HEM-3D (High Energy Milling Ellipse-3D Mention), XRF (X-Ray Fluorescene), XRD (X-Ray Difraction) and SEM (Scanning Electron Microscope). The precursors were made by adding 0.5 grams of polystyrene and 0.4 grams of MnO powder and Fe₂O₃ powder. The coating is carried out by using the spin coating method and temperature variations using a furnace. The result of this research is that the MnO-Fe₂O₃/PS nanocomposite coating made has the best photocatalytic properties at a temperature of 60ºC with a grain size of 168.73 nm. photocatalyst coating of nanocomposite MnO-Fe₂O₃/PS to produce an energy gap of 2.4 electron volts.
