Abstract
Cadmium sulfide improved with dimanganese copper oxide (Mn2CuO4/CdO) was prepared and applied this semiconductor nanocomposites in advanced oxidative processes via the photoelectrocatalytic efficiency for cephalexin degradation. The Z-scheme Mn2CuO4/CdO nanocomposites was characterized by FESEM, XPS, UV–vis, EIS, and XRD. The photocurrent response were conducted in to evaluate the photo generated in the degradation reaction. Mn2CuO4/CdO was obtained to displays better photoelectrocatalytic response compared to bare CdO; this result shows the role of other semiconductor oxide material as photoanode construction. The degradation of cephalexin in photoelectrocatalytic response is higher than the photocatalytic process. A possible catalysis mechanism was depicted using free radicals scavengers. It was observed that hydroxyl radical and holes contribute as the main role in antibiotic degradation. The Mn2CuO4/CdO was used as great antibacterial agent versus Gram+/−. The Mn2CuO4/CdO probe was used to determine of vitamin B1 in peroxidase activity. The limit of detection was 41.21 nM.
