摘要：

Redox-active cobalt-based metal-organic framework (MOP) with uniform micro-rods was synthesized by using electroactive 2,5-dihydroxyterephthalic acid (DOBDC) ligand. The Co/DOBDC micro-rods exhibited well-behaved redox events in pH 4.0 acetate buffer, which also showed high electrocatalytical activity for the reduction of hydrogen peroxide (H2O2) in physiological pH. Based on the Co/DOBDC, nonenzymatic sensor was presented for the determination of H2O2 with high stability, good repeatability, low detection limit and wide linear range. (C) 2015 Elsevier B.V.
