Investigators at South China University of Technology Discuss Findings in Fullerenes (Carbon nanotubes as catalyst for the aerobic oxidation of cumene to cumene hydroperoxide)

By a News Reporter-Staff News Editor at Science Letter -- A new study on Fullerenes is now available. According to news reporting out of Guangdong, People's Republic of China, by NewsRx editors, research stated, "The effective oxidation reaction system using the commercial carbon nanotubes (CNTs) as catalysts for the liquid aerobic oxidation of cumene to cumene hydroperoxide (CHP) under low temperature is reported in this paper. Several reaction parameters, including the temperature, catalyst content, oxygen flow rate and reaction time were carefully studied."

Our news journalists obtained a quote from the research from the South China University of Technology, "Under optimal conditions, cumene conversion of 24.1% with CHP selectivity of 88.4%, close to that of metal catalyst, was obtained. Cumene oxidation catalyzed by CNTs was proved a radical-involved reaction, and the outstanding catalytic performance was attributed to CHP decomposition catalyzed by CNTs to produce free radicals. Oxygenated functional groups on the surface of catalyst showed a negative effect on cumene oxidation due to the localization of electrons after the introducing of defects and oxygenated functional groups. CNTs as catalysts also showed desirable recyclability after five cycling tests."

According to the news editors, the research concluded: "This study not only provides an applicable method for selective oxidation of cumene to CHP, but also gives some useful information on catalytic role of CNTs-catalyzed liquid-phase oxidation reactions of aromatic hydrocarbons."
