摘要
For the first time Cu2O particles with different morphologies are synthesized by adopting a polyol process performed at different temperatures. SEM and TEM show that the samples obtained at 140 and 160 degrees C present a core-shell structure. XRD measurements indicate that both samples exhibit better crystallinity compared with the samples obtained at 120 degrees C. Results from charge-discharge experiments and cyclic voltammograms (CV) reveal that morphology and crystallinity play important roles in determining the electrochemical performance Of Cu2O samples.
