Abstract:

The importance of oxygen reduction reaction (ORR)in fuel cells and metal/air batteries is well–known. However,designing electrocatalysts with
high performance for ORR remains a challenge.In this work,three novel PdNi
–based composite materials, namely PdNi/(SnO2/KB600), PdNi/(SnO2/KB300) and
PdNi/VulcanXC72 are prepared by standard precipitation method.
The electrochemical activity of each catalyst for the ORR is studied in
alkaline media by voltammetry techniques using rotating disc electrode (RDE).From the RDE data at different rotation speeds and by using Koutecky–
Levich equation, the kinetic parameters of the ORR, such as number of exchanged electrons and kinetic current density,are calculated.
These results show that PdNi–based composite materials possess high electrocatalytic activity for reduction of oxygen in alkaline media.

Keywords:

oxygen reduction reaction; palladium nickel electrocatalyst; metal oxide support
