Abstract: 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.

Key words: cuprous oxide, morphologically controlled synthesis, photogradation, organic dye
