摘要：

The systematic and delicate geometry control of Cu2O nanostructures with different size can be achieved by simply tuning the dropping speed of NH2OH HCl, the volume of solvent and the concentration of NaOH. All the Cu2O nanocrystals exhibit better adsorption ability than granular active carbon on MO (methyl orange), and the hollow sphere Cu2O shows the best adsorption performance, MO with a concentration of 15 mg L-1 is completely absorbed by the hollow sphere Cu2O in 5 min. The gas detection sensitivity is also investigated and the hollow sphere structures exhibit the best gas-sensing response, and more importantly, at low temperature and even ppb level it also exhibits a remarkably high response, fast response, recovery time and good stability.
