摘要：
Microcrystals of cuprite (Cu2O) samples exhibiting octahedral and spherical morphologies were synthesised via a facile chemical method and were then characterised by X-ray powder diffraction and scanning electron microscopy. It was observed that the potassium sodium tartrate (KNaC(4)H(4)O(6)4H(2)O, PST) and gelatin addition had a prominent effect on the morphologies. The possible formation mechanism of Cu2O microcrystals was discussed based on the effects of PST and gelatin. Furthermore, the photocatalytic activities of the prepared Cu2O microcrystals were investigated by UV-vis spectrophotometry, demonstrating that their behavior was influenced by the different morphologies, and the Cu2O microspheres possessed the highest activity.
