Morphology Change in Cuprous Oxide Particle Synthesis with PVP:Effect of Reaction Temperature
(0) Cuprous oxides with different morphologies could be prepared by simply changing the reaction condition, such as the temperature.Here, we report the Cu2O morphological transforming from polyhedron to cube with the reaction temperature increasing from 35℃ to 65℃.At lower temperature, the polyvinylpyrrolidone (PVP) working as a crystal modifier which decreases the surface energy of facets (111) and (110), thus these high energy facets appear in relative low temperature.Facets (111) and (110) gradually diminished along with temperature increasing, while facet (100) expanded.The morphology became into cube from polyhedron.Cu2O particles synthesized at 65℃ are larger than those at 35℃.The UV-Vis extinction bands of the cuprous oxide synthesized in this research were red-shift with the increase of particle size.
