Investigation of adsorption behavior of Cu2O submicro-octahedra towards congo red

Abstract

Perfect cuprous oxide (Cu2O) nanocrystals with octahedron shape were successfully synthesized by a facile route without chemical additive in a short time. The products were characterized by X-ray diffraction (XRD) and field-emission scanning electron microscopy (FESEM). The adsorption ability of the products towards congo red (CR) as the pollutant was investigated and FTIR spectroscopy was employed to identify the adsorbed species. The adsorption behavior was analyzed based on the microstructure of Cu2O submicro-octahedra. © 2014 Xu Zhang et al.
