TiO₂ nanoparticles were homogeneously coated on multi-walled carbon nanotubes by hydrothermal deposition, this nano-composite may be a promising material for myoglobin immobilization in view of its high biocompatibility and large surface.The glassy carbon electrode modified with Mb-TiO₂/MWCNTs films exhibited a pair of well defined, stable and nearly reversible cycle voltammetric peaks.The electron transfer between Mb and electrode surface, Ks of 3.08 s^-1, was greatly facilitated in the TiO₂/MWCNTs film.The electrocatalytic reductions of hydrogen peroxide were studied, the apparent Michaelis-Menten constant is calculated to be 83.10 μmol/L, which shows a large catalytic activity of Mb in the TiO₂/MWCNTs film to H₂O₂.
