A process of producing a composite having carbon nanotubes is described where the carbon nanotube formation process of producing carbon nanotubes includes controlled heating of plant fiber materials in an oxygen-limited atmosphere. The plant fiber materials may be heated either cyclically or by rapid heating to produce the carbon nanotubes.

Methods for oxidizing organic compounds using hydroxyl radicals formed through redox cycling chelator-mediated Fenton chemistry are disclosed. The methods include generating a reactive oxygen species by contacting a redox cycling chelator with an oxygen containing oxidant and a transition metal species. By contacting the resulting reactive oxygen species with an organic compound, the organic compound is oxidized. The preferred transition metal species is a cationic transition metal, such as iron or copper. The disclosed methods may be used to degrade organic waste compounds and dyes, activate lignocellulosic materials for bonding and produce adhesive formulations.

A method of forming reactive oxygen species by solubilizing a metal ion from a metal oxy(hydr)oxide compound with an iron oxy(hydr)oxide solubilizing chelator to yield a first soluble metal ion chelate complex. The metal ion is transferred from the chelate complex to a free redox cycling chelator to form a second metal ion chelate complex which reduces the metal ion to a reduced metal species. The reduced metal species is reacted with an oxygen containing oxidant to yield a free redox cycling chelator and a reactive oxygen species. The reactive oxygen species may be used to oxidize a target substrate. The preferred metal ion is a cationic transition metal, such as iron or manganese. A preferred iron oxy(hydr)oxide solubilizing chelator is oxalic acid. The method is generally performed at acidic pH. Also provided is a method of protecting an organic composition from reactive oxygen species comprising impregnating the composition with a redox cycling chelator able to form a reduced metal ion chelate complex with a metal ion, the chelator present in an amount sufficient to protect the composition from degradation from reactive oxygen species such as hydroxyl radical or superoxide anion.
