The method comprises synthesizing metal oxide particles in situ in nominally-aligned arrays of carbon nanotubes (CNTs) after synthesis of CNTs. The particles can be SnO 2 particles or MnO 2 particles. A foam structure is further disclosed. The foam structure comprises nominally-aligned arrays of carbon nanotubes (CNTs) and a plurality of metal oxide particles associated with the nominally-aligned arrays of carbon nanotubes (CNTs). The CNTs have an original crystalline structure as grown and the CNTs with the metal oxide particles have a crystalline structure equal to the crystalline structure of the CNTs as grown.
专利号:US-7192567-B1 优先权日:1999-09-17 标题 :Precursor soot synthesis of fullerenes and nanotubes without formation of carbonaceous soot 发明人:REILLY PETER T A 权利人:UT BATTELLE LLC 摘要:The present invention is a method for the synthesis of fullerenes and/or nanotubes from precursor soot without the formation of carbonaceous soot. The method comprises the pyrolysis of a hydrocarbon fuel source by heating the fuel source at a sufficient temperature to transform the fuel source to a condensed hydrocarbon. The condensed hydrocarbon is a reaction medium comprising precursor soot wherein hydrogen exchange occurs within the reaction medium to form reactive radicals which cause continuous rearrangement of the carbon skeletal structure of the condensed hydrocarbon. Then, inducing dehydrogenation of the precursor soot to form fullerenes and/or nanotubes free from the formation of carbonaceous soot by continued heating at the sufficient temperature and by regulating the carbon to hydrogen ratio within the reaction medium. The dehydrogenation process produces hydrogen gas as a by-product. The method of the present invention in another embodiment is also a continuous synthesis process having a continuous supply of the fuel source. The method of the present invention can also be a continuous cyclic synthesis process wherein the reaction medium is fed back into the system as a fuel source after extraction of the fullerenes and/or nanotube products. The method of the present invention is also a method for producing precursor soot in bulk quantity, then forming fullerenes and/or nanotubes from the precursor bulk.

The method involves the synthesis of mixed metal nanoscale composites using low cost precursors which allow for the synthesis of desired nanocomposite materials with self-scarifying titanium or silica supports. The procedure does not require any surfactant or any need for pH controlled step. Applicants' method involves the in-situ generation of precursors and their simultaneous entrapment in a gel. This simple one pot synthesis allows for the synthesis of homogenous size, shape and distribution of targeted nanostructures. Further, this method can be applied for the preparation of various nanocomposite materials using different choices of metals and self-scarifying supports. Applicants also show that Pd, the noble metal based nanocomposite is feasible.

A ferrocene derivative of general formula (II) in which R1 and R2 have the abovementioned meaning, is reacted at a temperature -5 DEG C.< theta r<+15 DEG C., in the presence of AlCl3 with a halide or the anhydride of an acid of general formula (III) HOOC-(CH2)n-X, X and n having the abovementioned meaning. An acylating solution obtained by mixing AlCl2 and the acid halide or anhydride in CH2Cl2, whose temperature theta a is such that 5 DEG C.= theta r- theta a=15 DEG C., is progressively added to a solution of the ferrocene derivative (II) in CH2Cl2. The molar ratio of the acid halide or anhydride to the ferrocene derivative is between 0.99 and 1.01 and that of AlCl3 to the ferrocene derivative between 1.05 and 1.11. The mixture is then hydrolyzed and the crude product (I) is recovered by filtration followed by evaporation of CH2Cl2. This process enables a crude synthetic product to be obtained in a yield and with a purity which are high. The monohaloalkanoylferrocenes (I) are synthesis intermediates in pharmacy and in self-propulsion.
