Reaction Performance

We report a heterostructured Cu3N@CNT electrocatalyst for application in alkaline fuel cells. The size of well-dispersed Cu3N nanoparticles can be precisely controlled by ALD. Superior catalytic oxygen reduction reaction performance was achieved with a mixed two- and four-electron process.
