摘要:
A photocatalyst nanocomposite which can be used to destroying biological agents includes a carbon nanotube core, and a photocatalyst coating layer covalently or ionically bound to a surface of the nanotube core. The coating layer has a nanoscale thickness. A method of forming photocatalytic nanocomposites includes the steps of providing a plurality of dispersed carbon nanotubes, chemically oxidizing the nanotubes under conditions to produce surface functionalized nanotubes to provide C and O including groups thereon which form ionic or covalent bonds to metal oxides, and processing a metal oxide photocatalyst sol-gel precursor in the presence of the nanotubes, wherein a nanoscale metal oxide photocatalyst layer becomes covalently or ionically bound to the nanotubes.

摘要:
Polyhydroxyfullerenes (PHFs) having enhanced electron scavenging capabilities have a ratio of non-hydroxyl functional groups to hydroxyl functional groups that is less than or equal to 0.3. When combined with a semiconductor photocatalyst, such as titanium dioxide nanoparticles, the PHFs provide a photocatalyst for degradation of chemical and biological contaminates with an efficiency of at least twice that of titanium dioxide nanoparticles free of PHFs. The PRFs are included in these catalysts at a weight ratio to titanium dioxide of about 0.001 to about 0.003, whereas significantly lower and higher ratios do not achieve the highly improved photodegradation capability. PHFs outside of the desired structure are shown to be of little value for photodegradation, and can be inhibiting to the photocatalytic activity of TiO2. The enhanced electron scavenging PHFs can be employed as a component of materials for solar cells, field effect transistors, and radical scavengers.
摘要:
A method to release hydrogen from a material comprising hydrogen fixed fullerenes involves irradiating the hydrogen fixed fullerenes with electromagnetic radiation of sufficient intensity to release hydrogen rapidly upon irradiation. The intensity of the irradiation and/or the area of irradiation can be adjusted to control the rate and extent of hydrogen release. The hydrogen depleted material comprising hydrogen fixed fullerene can be hydrogenated to regenerate the material.
摘要:
Fullerenes, when irradiated with electromagnetic radiation, generate acoustic waves. A photoacoustic tomography method using a material comprising fullerenes is disclosed that includes irradiating the material with a radiation beam such as a laser. The resultant photoacoustic effect produced by the material is detected by at least one detector. A photoacoustic tomography system using a material comprising fullerenes is also described.
摘要:
Methods of stimulating an increase in biomass by stimulating the growth, lifespan and/or reproduction of organisms such as fungi, algae, plants, and other aquatic organisms are provided by applying an effective amount of functionalized fullerenes. For example, polyhydroxy fullerenes are effective at low levels of promoting the increase in biomass.

摘要:
Electromagnetic irradiation of functionalized fullerenes in an oxygen-free environment induces conversion of the functionalized fullerenes to carbon nanotubes, carbon nanohorns, carbon onions, diamonds and/or carbon schwarzites. The carbon nanotubes can be multi-wall carbon nanotubes. Advantageously, the subject invention can be used for in-situ synthesis of carbon nanostructures within a matrix to form a carbon nanostructure composite, where positioning of the carbon nanostructures is controlled by the manner of dispersion of the functionalized fullerenes in the matrix. Carbon nanotube comprising features, such as electrical connects, can be formed on a surface by irradiating a portion of a functionalized fullerene coating with a laser beam.
