Photocatalytic degradation of direct green & fast orange red dyes: Electrochemical sensor of lead using cupric oxide nanoparticles synthesized via sonochemical route
In this study, nanocrystalline cupric oxide was produced using a basic, low-cost sonochemical method (CuO). Through powder X-ray diffraction, the phase and nanocrystalline nature of CuO nanoparticles (NPs) were determined. The Kubelka-Monk function revealed that the band gap of CuO in diffuse reflec...

| description | In this study, nanocrystalline cupric oxide was produced using a basic, low-cost sonochemical method (CuO). Through powder X-ray diffraction, the phase and nanocrystalline nature of CuO nanoparticles (NPs) were determined. The Kubelka-Monk function revealed that the band gap of CuO in diffuse reflectance spectra (DRS) is 1.75 eV. Ingenious photocatalysts for the removal of the dyes Direct green (DG) and Fast orange red (F-OR) have been demonstrated to work with CuO NPs. To examine the photocatalytic characteristics of NPs under UV light and sunlight irradiation, Direct Green (DG) and Fast Orange Red (F-OR) dyes were utilised as traditional dyes. Direct green dye was found to be excited at 624.1 and 623.8 nm in UV and sunlight, while Fast orange red dye is excited at 496.8 and 495.1 nm. Lead in 0.1 N HCl solution was detected using the cyclic voltammetry (CV) method with a modified carbon paste electrode (MCPE). According to electrochemical performance, CuO is an advantageous sensing electrode material for an element like lead. |
