摘要： Carbon nanostructures are formed from a carbon precursor and catalytic templating nanoparticles. Methods for manufacturing carbon nanostructures generally include (1) forming a precursor mixture that includes a carbon precursor and a plurality of catalytic templating particles, (2) carbonizing the precursor mixture to form an intermediate carbon material including carbon nanostructures, amorphous carbon, and catalytic metal, (3) purifying the intermediate carbon material by removing at least a portion of the amorphous carbon and optionally at least a portion of the catalytic metal, and (4) heat treating the purified intermediate carbon material and/or treating the purified intermediate carbon material with a base to remove functional groups on the surface thereof. The removal of functional groups increases the graphitic content of the carbon nanomaterial and decreases its hydrophilicity.

摘要： Metal-containing colloids are manufactured by reacting a plurality of metal ions and a plurality of organic agent molecules to form metal complexes in a mixture having a pH greater than about 4.25. The metal complexes are reduced for at least 0.5 hour to form stable colloidal nanoparticles. The extended reduction time improves the stability of the colloidal particles as compared to shorter reduction times. The stability of the colloidal particles allows for colloids with higher concentrations of metal to be formed. The concentration of metal in the colloid is preferably at least about 150 ppm by weight.

摘要： Improved bi-metallic nanocatalysts are manufactured using a control agent to produce nanoparticles having a controlled crystal face exposure. The bi-metallic nanocatalyst particles are manufactured in a two-step process. In a first step, nanocatalyst particles are manufactured using the control agent and the primary metal atoms. The primary metal atoms and the control agent are reacted to form complexed metal atoms. The complexed metal atoms are then allowed or caused to form nanoparticles. The nanoparticles formed in the first step using the control agent have a desired crystal face exposure. In a second step, the secondary metal atoms are deposited on the surface of the primary metal nanoparticles. The secondary catalyst atoms maintain the same crystal face exposure as the primary metal nanoparticles.

摘要： The carbon nanomaterials and methods relate to methods for causing carbon nanospheres to be readily dispersible in a material. The carbon nanospheres are rendered dispersible using a cationic surfactant. The surfactant includes one or more cationic group that can bond to the surface of the carbon nanospheres, without detrimentally affecting the unique properties of carbon nanospheres. The dispersiblecarbon nanospheres can be dried ( i.e. , solvent is driven off) while maintaining their dispersibility in solvents and other materials.

摘要： The particle sizes of agglomerates of carbon nanospheres are reduced by dispersing the carbon nanospheres in an organic solvent. The carbon nanospheres are multi-walled, hollow, graphitic structures with an average diameter in a range from about 10 nm to about 200 nm, more preferably about 20 nm to about 100 nm. Spectral data shows that prior to being dispersed, the carbon nanospheres are agglomerated into clusters that range in size from 500 nm to 5 microns. The clusters of nanospheres are reduced in size by dispersing the carbon nanospheres in an organic solvent containing at least one heteroatom (e.g., NMP) using ultrasonication. The combination of organic solvent and ultrasonication breaks up and disperses agglomerates of carbon nanospheres.
