文摘

Pd-poly(3,4-ethylenedioxythiophene) (PEDOT)-based electrocatalytic materials are obtained by coupling Pd ion reduction with oxidation of pre-reduced PEDOT coatings. Electroless metal deposition is carried out in single or triple electroless deposition steps resulting in Pd NPs with mean size ranging between 12 and 22 nm, respectively. The proposed method of dispersing the Pd catalytic phase provides the opportunity to obtain high electrocatalytic currents with Pd loadings as low as 10 μg cm−2. The Pd-PEDOT catalyst obtained by triple-step metal deposition shows stable voltammetric behavior with respect to glycerol oxidation in alkaline solution. The established mass activity is between the highest values achieved at Pd-electrocatalysts without involving additional electrocatalytic materials or special supports.
