摘要:	摘要： Porous graphitic carbon nitride/carbon composite spheres were synthesized using melamine and cyanuric acid, and glucose as the carbon nitride and carbon precursor, respectively. The 3D hierarchical composites efficiently catalyzed the oxygen reduction reaction with an onset potential of 0.90 V and a kinetic current density of 23.92 mA cm −2 . These merit their promising applications in fuel cells and metal-air batteries. Porous graphitic carbon nitride/carbon composite spheres synthesized from glucose, melamine and cyanuric acid precursors via a template-free route efficiently catalyze the electrochemical oxygen reduction. 其他題名： Chem Commun (Camb) 出版者： England 出版日期： 2016-01-01 出處： Chemical communications (Cambridge, England), 2016-01, Vol.52 (8), p.1725-1728 資源來源： Royal Society of Chemistry 識別號： ISSN: 1359-7345 識別號： ISSN: 1364-548X 識別號： EISSN: 1364-548X 識別號： DOI: 10.1039/c5cc08897f 識別號： PMID: 26666314
