Synthesis of the crystalline porous copper oxide architectures derived from metal-organic framework for electrocatalytic oxidation and sensitive detection of glucose

The porous CuO architectures have been successfully synthesize by the effective transformation of a Cu-BTC metal-organic frameworks (MOFs) through a facile heating treatment. The as-synthesized porous CuO architectures exhibit high electrocatalytic activity toward the glucose oxidation. When evaluated as a nonenzymatic glucose biosensor, the porous CuO architectures manifest fast response within 1.3 s, wide linear range from 0.5 mu M to 2.8 mM, low detection limit of 0.1 mu M (signal-to-noise ratio of 3), high sensitivity up to 934.2 mu A mM(-1) cm(-2) as well as favorable reproducibility.
