Abstract

Metal oxide semiconductors are one type of nanocomposites used for microelectronic circuits, piezoelectric devices, fuel cells, sensors, catalysts, surface coatings to prevent corrosion, and solar cells. ZnO-CuO is a type of metal oxide semiconductor composite. The combination of these two metals can produce a composite that can be used for catalysts and antibacterial substances. Photodegradation method is a textile dyestuff treatment which breaks down organic dyes into simpler compounds. The method used in the synthesis of ZnO-CuO composites is an electrochemical method using an acetic acid electrolyte solution. In this study acetic acid was used with the concentration of 0.15 and 0.3 M. The resulting composites were analyzed using XRF, XRD and FTIR analysis. The composites are used as methyl orange photodegradation catalysts with different time variations 0 to 150 minutes. The absorbance of the degradation solution was measured by UV VIS Spectrophotometer. The effectiveness produced from the composites with concentrations of 0.3 M acetic acid was 21.69%, while the effectiveness produced from the composites with concentrations of 0.15 M was 16.58%.
