By a News Reporter-Staff News Editor at Life Science Weekly -- Fresh data on Chalcogens are presented in a new report. According to news reporting originating in Lanzhou, People's Republic of China, by NewsRx journalists, research stated, "A new nanocatalyst has been synthesized by a simple and effective wet chemical method confined magnetic cobalt nanoparticles within carbon nanotubes (CNTs). We characterized the catalysts by transmission electron microscopy (TEM), X-ray powder diffraction (XRD) and vibrating sample magnetometer (VSM)."
The news reporters obtained a quote from the research from Lanzhou University, "The TEM results demonstrated that the cobalt nanoparticles were filled into the CNTs successfully. In the meantime, the CNTs mesostructure were not destroyed in multistep synthetic procedure. In the catalytic activity test, liquid phase epoxidation of styrene by molecular oxygen was carried out at atmospheric pressure employed Co/CNTs (in) catalysts. The results showed that styrene conversion over 99% and epoxide selectivity of 93% for 1 h reaction."
According to the news reporters, the research concluded: "The catalysts can be easily separated from the reaction mixtures by external magnet, and reused three times without significant loss in catalytic activity."
