Catalyst preparation by combustion synthesis for electrochemical hydrocarbon devices

摘要

Metals and ceramics can behave as active electrocatalyst materials,particularly in hydrocarbon oxidation in anodic reaction fuel cells.Combustion synthesis is a very reliable,fruitful and rapid synthesis method to produce metals,ceramics and cermets with low particle size and high specific surface area.This work describes the preparation of nanoparticle Pt/Ru alloys,ceramic perovskites such as Sm_0.95CoO_(3-delta),and Sm_0.95CoO_(3-delta)/Pt cermets,and shows how promising these materials can be in the role of electrochemically active materials.
