摘要：
Titanium-supported nanoporous palladium catalyst (Pd/Ti) was prepared by a hydrothermal method using PdCl(2) as a precursor, ethylenediamine tetraacetic acid (EDTA) as a ligand, and formaldehyde as a reduction agent. Complex Pd-EDTA(2-) is favorable for the formation of Pd particles with nanoscale sizes. The electroactivity of the Pd/Ti catalyst towards the electroreduction of hydrogen peroxide in 1 mol/L NaOH solution was evaluated by voltainmetric techniques. Both linear scan voltammetric and chronoamperometric data present significantly large steady-state reduction current density of the hydrogen peroxide electroreduction on the prepared Pd/Ti catalyst. The results show that the prepared Pd/Ti catalyst is an effective electrocatalyst for the electroreduction of hydrogen peroxide in alkaline media.
