The Effect of the Reducing Sugars in the Synthesis of Visible-Light-Active Copper(I) Oxide Photocatalyst

In the present work, shape tailored Cu2O microparticles were synthesized by changing nature of reducing agent and studied subsequently. d-(+)-glucose, d-(+)-fructose, d-(+)xylose, d-(+)-galactose, d-(+)-arabinose chosen as agents due to their different abilities. The morpho-structural characteristics X-ray diffraction (XRD), scanning electron microscopy (SEM), diffuse reflectance spectroscopy (DRS), while photocatalytic activity was evaluated methyl orange degradation under visible light (120 min). results show that number carbon atoms in sugars affect morphology particle size (from 250 nm 1.2 µm), differences degree crystallinity also found. highest observed when glucose used agent.
