Three-step method with self-sacrificial Co to prepare a uniform 5 nm-scale Pt catalyst for the oxygen reduction reaction

The catalytic activity of Pt-based catalysts for fuel cells is largely determined by the particle size and the dispersion of Pt. Normally, the electrodeposition of Pt cannot avoid a large particle size and agglomeration. For ensuring uniformity and a small size in the 5 nm scale of Pt, a three-step...
