Hollow carbon spheres (HCS) have been employed as supporting materials for Pt, Ag, and Au nanoparticles (NPs) in theoxygen reduction reaction (ORR). The NPs Pt, Ag, and Au have been hydrothermally coated on HCS uniformly. The diameterof the Pt, Ag and Au NPs ranges between 11 and 32 nm, with the loading of 4.58, 4.73, and 4.07 wt.%, respectively. Itis found that Pt, Ag, and Au/HCS exhibit stable catalytic activity after 5000 CV scanning and follow a four-electron routein the ORR. Among them, Tafel plots show that Ag/HCS has the fastest kinetic rates and Pt/HCS has the largest eff ectiveactive area from CV curve. Hence HCS provides a stable supportive material for Pt, Ag, Au nanoparticle catalysts in theORR due to its nanopores structure and large surface area.
