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

Abstract

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 1.3s, wide linear range from 0.5μM to 2.8mM, low detection limit of 0.1μM (signal-to-noise ratio of 3), high sensitivity up to 934.2μAmM−1cm−2 as well as favorable reproducibility.
