Generation of the C60 radical cation via electron transfer reaction. A pulse radiolysis study

Redox processes and alkylation reactions of fullerene C60 as studied by pulse radiolysis

“…We could also not confirm any radical cation band at around 650 nm which in benzene-CCU solutions was reported to be still visible at 10-20 gs after the pulse. 20 In irradiated CCI4 solutions this wavelength range is dominated by long-lived absorption changes which are probably associable with radical adducts.…”

On the Action of γ Radiation on Solid C60and C70Fullerenes: A Comparison with Graphite Irradiation

“…Pulse radiolysis studies have been conducted also at room temperature in aromatic solvents (5,6) and in halogenated solvents (7)(8)(9)(10). In most cases the formation of triplet state of CSO was observed with decay to the radical cation state in the case of the halogenated solvents (7). In this context, the radiolysis of CSO in CC14 produces directly radical adducts with CC4 fragments but no excited states of fullerene have been observed (7)(8)(9)(10).…”

An interesting work (6) about Cm and C70 radiolysis in aromatic and aliphatic solvents concluded that Cm and C 7 , , are remarkably stable to y radiation since the G(-Cm) and G(-C70) were found very low.…”

“…The former specie has been produced by photoionization while the latter specie by electron capture.

Advanced Oxidation Kinetics and Mechanism of Preservative Propylparaben Degradation in Aqueous Suspension of TiO2 and Risk Assessment of Its Degradation Products

“…A detailed description of pulse radiolysis has been presented elsewhere. 21 A Xenon lamp was used as the light source, which was passed through a quartz cell perpendicularly with electron beam. The transmitted light was collected by a monochromator equipped with a photomultiplier (R955, Hamamatsu, Japan), and the output signal was recorded by a personal computer with a digital oscillograph (LeCroy wavemaster 8600A, NY, USA).…”
