Extraction and purification of dimeric fullerene oxides from fullerene soot

Article Abstract:

An experiment was conducted to extract dimeric fullerene oxides in the fullerene soot by using hydrothermally initiated dynamic extraction process. This process requires treating the soot hydrothermally before the extraction by organic solvent. Compared to Soxhlet extraction with organic solvents, this process was 40 times more efficient. Moreover, the analyses showed that the extract includes higher fullerene oxides in addition to dimeric fullerene oxides. Purification procedures for individual fullerene oxide are discussed.

Photocatalytic oxidation of 2-propanol on TiO2 powder and TiO2 monolayer catalysts studied by solid-state NMR

Article Abstract:

The adsorption and photocatalytic oxidation of 2-propanol is examined by solid-state NMR spectroscopy over TiO2 powder and a TiO2 monolayer catalyst anchored on porous Vycor glass. The slow photooidation rate of 2-propanol to CO2 on TiO2/PVG resulted from the availability of only the first, slow reaction route.

Purification of MWNTs combining wet grinding, hydrothermal treatment, and oxidation

Article Abstract:

A combination of wet grinding, hydrothermal treatment and oxidation process are used to describe a purification technique for multi-walled carbon nanotubes (MWNTs). This purification technique is believed to be able to revive research interest in MWNTs and bring about major advances in their application.
