Abstract
Platinum nanoparticles were deposited on boron-doped diamond substrate by electroless method without pre-activation. The mechanism of this deposition is a galvanic process along with a chemical process. Platinum particles are in nanoscale with diameter around 30-50 nm and height of around 3 nm observed from AFM and SEM images. The electrochemical activity of Pt nanoparticles was evaluated by cyclic voltammograms of hydrogen desorption process in 0.5 M H2SO4. The deposited platinum shows great stability in subsequent cycling in sulfuric acid and exhibits a high selectivity toward H2O2 detection in the range of 1 to 400 μM compared with those produced by electrochemical deposition.
