Preparation and electrochemistry of boron-doped diamond nanoparticles on glassy carbon electrodes

摘要

Boron-doped diamond (BDD) was prepared in nanosize particles and they were used as a support for noble metal-based nanoparticles. Nanosize platinum oxide was deposited on diamond nanoparticles as well as on boron-doped diamond nanoparticles by the sol-gel method. Cyclic voltammetric results showed an improvement in conductivity as well as in surface capacitance when diamond nanoparticles were doped with boron. The X-ray photoelectron spectroscopy boron binding energy peak showed B_0, which is consistent with the electrochemical characterization. Platinum oxide deposition was studied by cyclic voltammetry with an improvement when BDD nanoparticles were used as a support.
