Nanodiamond(ND)can be used as catalyst carrier in catalytic area because of its excellent thermal conductivity,thermal stability and specific area.This paper reviews the application of microwave coated ND in fuel cells,focusing on the preparation of platinum catalyst which is carried by TiO
2/ND(GND,graphic nano-diamond)and TiN/ND,and Co-N Co-doped ND non-platinum Co-N-C/ND catalyst.Phase,morphology and composition of above products are studied by using XRD and TEM,and the electrochemical activity of Pt/TiO
2/ND(GND),Pt/TiN/ND and Co-N-C/ND catalyst is tested by electrochemical experiment.Resultsshow that coating ND by using microwave will enhance its performance and widen its application in catalyst area.
