Cu/Cu2O nanostructures derived from copper oxalate as high performance electrocatalyst for glucose oxidation

摘要

Porous nanomaterials are classified as a kind of materials with great potential for development in the field of electrocatalysis,but there is still room for further improve ment as catalysts.We develop a threedimensional(3D)porous structure of Cu/Cu2O as an electrocatalyst for the glucose oxidation reaction(GOR)using the method of calcining the precursor CuC2O4·2H2O in N2.The obtained porous Cu/Cu2O nanostructure can provide more opportunities for effective reactions between particles,which can explain their efficient electrocatalytic performance.Additionally,the as-synthesized Cu/Cu2O nanostructure exhibits outstanding electrocatalytic performance for the glucose,including good stability,excellent sensitivity and remarkable selectivity.
