Abstract:

Cu2O octahedrons, rhombic dodecahedrons and cubes were prepared and evaluated for the reduction of hexavalent chromium under visible light irradiation. The specific activity of Cu2O with different crystal planes followed the order {111} > {110} > {100}. The surface capping ligands of octahedral and rhombic dodecahedral Cu2O have no blocking effect on their photocatalytic performance.

Key words: Hexavalent chromium, Facet, Photocatalysis, Visible light, Cuprous oxide
