Abstract
Hollow molybdenum carbide sphere (HMoCS) is synthesized by dispersing MoC particles in the shell of hollow carbon spheres. The typical HMoCS has the specific surface area of 542Â m2/g, small-sized MoC particles of 15Â nm in diameter and hollow spherical structure, which favor mass transfer and dispersion of smaller Pt particles, and then lead to excellent catalytic activity and stability of the Pt/HMoCS electrocatalyst for both ORR and MOR. In addition, the electron transfer or interaction force between MoC and Pt is believed to be the origin of the smaller Pt particles and the promotion effect of HMoCS on Pt.
