- Abstract
- Recently,enormousresearch effortshavebeen focused on thedevelopmentofnon-preciouscatalyststo
replacePtforelectrocatalyticoxygen reduction reaction (ORR),and toreducethecostofproton exchange
membranefuelcells(PEMFCs).Inrecentyears,heteroatom (N,B,andP)dopedcarbonnanostructureshave
been received enormous importance as a non-precious electrodematerials foroxygen reduction.Doping of
foreign atom intocarbon isabletomodify electronicpropertiesofcarbon materials.In thisstudy,nitrogen
and boron doped carbon nanostructures were synthesized by using a facile and cost-effective thermal
annealing routeand prepared nanostructures were used as a non-precious electrocatalysts forthe ORR in
alkalineelectrolyte.Thenitrogendopedcarbonnanocapsules(NCNCs)exhibitedhigheractivitythanthatofa
commercialPt/C catalyst,excellentstability and resistance to methanoloxidation.The boron-doped carbon
nanostructure(BC)prepared at900 °C showed higherORR activity than BCsprepared lowertemperature
(800,700°C).Theheteroatom doped carbon nanomaterialscould bepromising candidatesasa metal-free
catalystsforORR inthePEMFCs.
