Abstract

We report a facile method for the synthesis of cuprous oxide nanocrystals with three different structure. High surface roughness spheres, self-assembly layered Cubic and snowflake nanocrystals can be synthesized directly by hydrothermal method. F127, CTAB and EDTA was used to be a precise control of the nanocrystal morphology. Different proportions of water and ethanol mixed together was used as solvent. All three samples displayed activity toward photodegradationof rhodamine B molecules, self-assembly layered Cubic nanocrystal exhibited a higher extent of the photodecomposition reaction. We inferred that the {111} faces Cu2O nanostructures are catalytically more active. These nanocrystals provide a comparing in various properties as a function of the crystal structures. The photocatalytic properties of the prepared nanocrystals are studied showing enhanced photocatalytic activities. The improced activities are considered to be related to the special structure and edge sites on the particles.
