Sichuan University Details Findings in Nitrogen

February 7, 2014

By a News Reporter-Staff News Editor at Science Letter -- Investigators publish new report on Nitrogen. According to news reporting originating in Chengdu, People's Republic of China, by NewsRx journalists, research stated, "Carbon nanotubes (CNTs) and nitrogen-doped carbon nanotubes (N-CNTs) were synthesized using a floating catalyst chemical vapor deposition method and characterized by scanning electron microscopy (SEM), transmission electron microscopy, Raman and X-ray photoelectron spectroscopy. The study found that the as-prepared CNTs and N-CNTs showed different discharge capacity as cathode materials in Li-air battery."

The news reporters obtained a quote from the research from Sichuan University, "To further study the reason why N-doping improves the electrochemical performance exceptionally, the discharge products on the two kinds of nanotubes were detected by SEM, XRD and Raman. SEM study showed, for the first time, that more uniform distribution of discharge products on the surface of CNTs arising from N-doping affected the boost of discharge capacity, a result which was discussed in detail."

According to the news reporters, the research concluded: "In comparison to non-doped CNTs, nitrogen doping was considered to be a promising way to improve the performance of carbon based cathode material for Li-air batteries."
