Studies of oxygen reduction activity and stability of carbon-supported PdNi and PdCu nanoparticles of different compositions
(2018-02-23) [Tese de doutorado]
The slow kinetics of the oxygen reduction reaction is the main cause of the severe performance losses of fuel cell cathode. Pt is the most active pure metal to catalyze this reaction. However, because of their limited ...
Surface structure and electronic properties of carbon supported PdAu nanoparticles and their catalytic behavior toward the oxygen reduction reaction
(2018-03-14) [Tese de doutorado]
Carbon supported PdAu nanoparticles with different Au contents (20-50% in atoms) were synthesized using a procedure carried out in a liquid two-phase system. As-prepared materials presented similar average particle diameter ...
