This review provides a brief summary of research progress in Cu2O with different morphologies, including nanocrystals and nanocages and nanoframes. The synthesis and research development, including one-dimension Cu2O structures,were emphatically introduced. The fabrication methods of Cu2O were compared and the key steps of synthesis were pointed out. Furthermore,the properties of photogradation of different crystals were discussed,it indicated that Cu2O crystals with more photoactive {110} planes or polyhedral crystals with more high-index facet have higher photocatalytic performance for dye gradation. Finally,ways to prepare different morphology Cu2O were summarized and the mechanism of morphologically controlled synthesis and the synthesis of Cu2O with more crystal faces and nanocage with integrated crystal face are very important fundamental research. The main problems of Cu2O crystals for the photogradation application are the poor stability and low efficiency.
