Study Data from China University of Petroleum Update Knowledge of Materials Science

February 11, 2014

By a News Reporter-Staff News Editor at Journal of Technology -- Current study results on Materials Science have been published. According to news originating from Qingdao, People's Republic of China, by VerticalNews correspondents, research stated, "Ruthenium/mesoporous carbon (Ru/MC) composites for supercapacitors were synthesized from RuCl3 and peanut shell-derived MC by a microwave-assisted heating glycol reduction method. The specific capacitance of obtained Ru/MC composite increased with the increasing Ru mass loaded, maintaining 287 F g(-1) even after 1000 cycles at 20% loading of Ru for Ru-20/MC."

Our news journalists obtained a quote from the research from the China University of Petroleum, "The contribution of Ru nanoparticles reached 48.7% of the total capacitance. The energy density of Ru-20/MC capacitor in 6 M KOH electrolyte only dropped from 10.5 Wh kg(-1) to 9.8 Wh kg(-1) with the energy density retention of 93.3% after 1000 cycles, showing excellent cycle stability."

According to the news editors, the research concluded: "The results indicate that the one-step microwave-assisted glycol reduction of RuCl3 is a simple technique to the preparation of high performance Ru/MC composites for supercapacitors."
