Abstract
Three-dimensional (3D) porous Cu2O microspheres were successfully synthesised by a simple template-free solvothermal method. Systematic studies showed that solvent, precipitator and temperature reaction parameters played a key role in controlling the morphology and structure of Cu2O. The crystallisation, morphology and composition of the as-prepared Cu2O was characterised by X-ray diffraction, a scanning electron microscope and energy-dispersive spectroscopy, respectively. It revealed that the 3D porous Cu2O microspheres were built from small 2D nanosheets with a thickness of 50–80 nm. Cyclic voltammetry was applied to investigate the electrochemical performance of the products. It was found that the 3D porous Cu2O microspheres possessed high electrocatalytic activity. The growth mechanism of the 3D porous Cu2O microspheres was proposed with a 3D molecule model.
