Mesoporous SBA-15 was prepared by using Pluronic P123 triblock copolymer as structure-directing agents and Au-modified mesoporous SBA-15 (Au-SBA-15) was synthesized by a Deposition-Precipitation methods. The surface of glass carbon was modified with Au-SBA-15 material (named Au-SBA-15/GC electrode), then hemoglobin (Hb) was immobilized on Au-SBA-15/GC electrode (named Hb/Au- SBA-15/GC electrode). The Rb/Au-SBA-15/GC electrode was applied to electrochemical determination of different concentration Of H2O2 solution. An oxidation peak at 0.95 V was observed, and the peak current was found to be increased with H2O2 concentration increasing. The results indicate that the Hb/Au-SBA-15/GC modified electrode exhibited certain electrocatalytic activity.
