Data on Nitrogen Described by Researchers at University of Jinan

June 24, 2014

By a News Reporter-Staff News Editor at Life Science Weekly -- Researchers detail new data in Nitrogen. According to news reporting from Guangdong, People's Republic of China, by NewsRx journalists, research stated, "Nitrogen-doped carbon nanomaterials have been attracted increasing research interests in lithium-O-2 and Zinc-O-2 batteries, ultracapacitors and fuel cells. Herein, nitrogen-doped graphitic carboncages (NGCs) have been prepared by mesoporous Fe2O3 as a catalyst and lysine as a nitrogen doped carbon source."

The news correspondents obtained a quote from the research from the University of Jinan, "Due to the catalysis of Fe2O3, the N-GCs have a high graphitization degree at a low temperature, which is detected by X-ray diffraction and Raman spectrometer. Simultaneously, the heteroatom nitrogen is in-situ doped into carbon network. Therefore, the excellent electrocatalysis performance for oxygen reduction reaction is expected."

According to the news reporters, the research concluded: "The electrochemical measurement indicates that The N-GCs for oxygen reduction reaction in O-2-saturated 0.1 mol L-1 KOH show a four-electron transfer process and exhibit excellent electrocatalytic activity (E-ORR = -0.05 V vs. Ag/AgCl) and good stability (i/io = 90% at -0.35 V after 4000 s with a rotation rate of 1600 rpm)."
