Facet-dependent performance of Cu2O nanocrystal for photocatalytic reduction of Cr(VI)

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.

Graphical AbstractCatalysis by Cu2O nanocrystals with different morphology for the photoreduction of Cr(VI) showed that the surface capping ligands of octahedral and rhombic dodecahedral Cu2O have no blocking effect and the activity of different facets was ranked {111} > {110} > {100}.Figure optionsDownload full-size imageDownload as PowerPoint slide
