Photocatalytic degradation of malachite green dye under UV mild irradiation using calcium-doped ceria nanoparticles A tentative mechanism to the photocatalytic bleaching of alizarin pink and gentian violet is proposed. Cuprous oxide (Cu two O) nano-crystallites with distinctive dimensions were ready through electrolysis system and characterised by X-ray powder diffraction (XRD) https://zbigniewu107qgn3.blogdomago.com/profile
