Findings from University of Kebangsaan Provides New Data about Chalcogens

June 24, 2014

By a News Reporter-Staff News Editor at Life Science Weekly -- Data detailed on Chalcogens have been presented. According to news reporting out of Selangor, Malaysia, by NewsRx editors, research stated, "Metal-free nitrogen-doped carbon nanotube (NCNT) catalysts were synthesised via chemical vapour deposition with ethylenediamine and iron phthalocyanine. The electrochemically active NCNT was studied via thin-film rotating-ring disk voltamogram analysis to elucidate the optimum loading of catalysts for oxygen reduction reaction (ORR) in 0.1 M KOH electrolyte."

Our news journalists obtained a quote from the research from the University of Kebangsaan, "In this study, the activity and stability of NCNT at elevated temperature were investigated. The current limiting plateau was achieved with loading above 500 mu g/cm(2) on glassy carbon tip with insignificant change in onset potential (c.a. +0.9 V vs RHE). The highest electron transfer number of 3.90 was obtained and it was found comparable to n = 3.95 on 130 mu g/cm(2) Pt/C catalysts."

According to the news editors, the research concluded: "The subjection to cell's temperature from 298K to 343 K showed improved activity and was found stable above 323 K."
