Chataliytic activity of nano ZnO/Cu for degradation humic acid under ilumination outdoor light

One of the photocatalysts that is being developed for the degradation of humic acid is ZnO, because it is cheap, easy to obtain and the synthesis process is easy, large size ZnO has several disadvantages such as small surface area and energy band gap which are not suitable when applied to visible light. The research developed a method of making zno in nanometer size and composting to reduce bandgap. The maximum degradation of humic acid at nano ZnO doped Cu 7% which is equal to 54.12%. Nano characterization of nano ZnO doped Cu 7% doping using XRD and DRS UV-Vis spectra was found to be 27 nm and bandgap 5.27 eV.
