carbon 新文：Active Sites in Animal Biomass-Modified on Carbon Nanospheres-ORR
|
|||||
|
Exploration of the catalytically active site structures of animal biomass-modified on cheap carbon nanospheres for oxygen reduction reaction with high activity, stability and methanol-tolerant performance in alkaline medium Chaozhong Guo , Wenli Liao, Zhongbin Li, Changguo Chen CA R B O N 8 5 ( 2 0 1 5 ) 2 7 9 –2 8 8 (此文共10页，引用了50篇参考文献）。从简单易得的动物血出发，制备出了廉价的碳纳米微球，用于碱性条件下氧还原反应（ORR），具有高活性、高稳定性的特点，能启发我们从事研究的人开动脑筋，寻求自然界中大量存在、特别是废弃的东西，可能是相当有用的资源——希望能有所脾益。 ABSTRACT Nitrogen-doped carbon materials are known to exhibit good electrocatalytic activity for the oxygen reduction reaction (ORR). However, the structure of the active site for the ORR remains unknown. In this work, a series of nitrogen-doped carbon nanospheres (N-CNSs) were successfully prepared by using porcine blood protein as specific nitrogen source at different pyrolysis temperatures. The results show that the catalyst with a higher percentage of the planar N species (83.5% in total nitrogen content), possesses outstanding ORR electrocatalytic activity close to the commercial 40% Pt/C catalyst in alkaline media, and significantly superior stability and immunity for methanol crossover than that of 40% Pt/C. Metal Fe particles in the precursor can facilitate the partial transformation of oxidized N to planar N and the joint incorporation of planar pyridinic and pyrrolic N groups into the carbon matrix during high-temperature pyrolysis, which further produces more defective and exposed edges in the carbon structure. It is here proposed that both planar pyridinic and pyrrolic nitrogen atoms may be the N functionalities that are most responsible for the ORR electrocatalytic activity and can function as ORR active sites for as-prepared catalysts.
