  • Publication number: 20130175182
    Abstract: A process for the transformation of carbon nanotubes (CNTs) to nanoribbons composed of a few layers of graphene by a two-step electrochemical approach is disclosed in this invention. This consists of the oxidation of CNTs at controlled potential, followed by reduction to form graphene nanoribbons (GNRs) having smooth edges and fewer defects, as evidenced by multiple characterization techniques, including Raman spectroscopy, atomic force micro-scopy, and transmission electron microscopy. This type of ‘unzipping” of CNTs (single-walled, multi-walled) in the presence of an interfacial electric field provides unique advantages with respect to the orientation of CNTs, which might make possible the production of GNRs with controlled widths and fewer defects. The extent of oxidation was confirmed by various characterization techniques like XRD, XPS and Raman spectroscopy. In the second step of experiments, the CNT oxide were reduced for different periods such as 4, 8, 12 hours at fixed negative potentials of ?0.

  • Publication number: 20090008262
    Abstract: The subject invention provides a potentially economically viable method for the preparation of reactive superoxide ion in deep eutectic solvents (DES). The superoxide ion can be used for many applications, e.g. the degradation of hazardous chemicals at ambient conditions or in the synthesis of some special chemicals, e.g. carboxylic acids, aldehydes, and ketones from the corresponding alcohols. The superoxide ion can be formed by either the electrochemical reduction of oxygen in DES or by dissolving Group 1 (alkali metals) or Group 2 (alkaline earth metals) superoxides, e.g. potassium superoxide, in DES, with/without chemicals used for the enhancement of the solubility of the metal superoxide in the DES, e.g. crown ethers.

  • Patent number: 6478946
    Abstract: A method of preparing organic acids (fulvic, humic, and ulmic) for use as an electrolyte for producing high ionizations of precious metals (such as silver) which entails leaching out the organic acid from its source, stabilizing the organic acid first with ascorbic acid followed by sodium benzoate, removing cations, and using the organic acid as an electrolyte. A precious metal (such as silver) is used as a sacrificial electrode in this electrolyte. A non-sacrificial electrode could either be the same precious metal or an inert non-precious metal (titanium or graphite carbons). If the same material is used for the non-sacrificial electrode as for the sacrificial electrode, the size of each electrode may be about the same. If different material is used for the non-sacrificial electrode, its size should be larger that of the sacrificial electrode. Current at about 2 or more volts is applied to the electrodes and the ionization process begins yielding high concentrations of ionized precious metals.

  • Patent number: 5965003
    Abstract: CMPO is safely, reliably and rapidly decomposed under mild conditions. A CMPO-containing substance is emulsified in an electrolyte comprising an oxidation promoter (silver ion) by an emulsifier in an emulsifying tank, this electrolyte comprising the CMPO-containing substance is supplied to an anode chamber, and an electrolytic oxidation reaction is performed by passing an electric current. By emulsifying the CMPO-containing substance, the surface area of CMPO in contact with electrolyte is increased, and electrolytic decomposition is thereby promoted. As sufficient CMPO decomposition is not obtained by passing the emulsion only once through an electrolysis tank 1, a batch oxidation method is employed wherein an anolyte is recirculated by a recirculating pump 3a through the anode chamber, a constant temperature bath 7a and an emulsifying tank 6, so that electrolysis is performed with the CMPO-containing substance permanently emulsified in the electrolyte.
