Abstract: The shape-controlled hollow sphere Cu2O nanomaterials were prepared by one-step solvothermal method, and used Cu(NO3)2·3H2O as raw material, ethylene glycol as reductant and polyvinylpyrrolidone (PVP) as surfactant. In this study, the influence of different mass ratios of Cu(NO3)2·3H2O and PVP (wCu(NO3)2·3H2O/wPVP) and reaction time on the crystal structures, morphologies, surface area and optical properties of Cu2O was researched. The photocatalytic mechanism of Cu2O nanocrystals are also investigated. The results show that the photocatalytic activity of Cu2O hollow spheres covered by nano-thorns is best when wCu(NO3)2·3H2O/wPVP=45, and at the 1 h of irradiation, the photodegradation efficiency of methyl orange solution can reach up to 94.3%.
