Herein, Cu₂O with different morphology were successfully synthesized by simply adjusting the copper sources via a seed-medium process. Cu₂O cubes with uniform size and stacked octahedrons (stacked by the self-assembly of cubic Cu₂O) were obtained. The growth mechanism of cubes and stacked octahedrons were studied and applied to non-enzymatic glucose detection. The obtained electrode exhibited excellent capability toward the glucose oxidation. The S-Cu₂O modified electrode showed the highest sensitivity of 2864 μA m·M⁻¹ cm^-2, the N-Cu₂O modified electrode exhibited the widest linear range of 0.05–7.65 mM and the lowest LOD of 0.5 μM. Meanwhile all the samples showed fast response time. The S-Cu₂O and N-Cu₂O modified electrode also exhibited good selectivity and stability. Thanks to these obvious advantages, the modified electrodes have a promising prospect in practical applications.
