Additive for liquid fuels, fuel compositions based on the additive, and methods of manufacture

Abstract

A nanostructure includes a plurality of substantially spherically curved carbon layers having diameters in a range of 1 nanometer to 1000 nanometers and a plurality of nitrogen atoms attached to an outer convex side of the carbon layers. A composition of matter includes a liquid fuel and an additive including at least one liquid and a plurality of carbon nano-onions. A method of fabricating an additive for liquid fuel includes creating a carbon based material using a plasma in an environment including at least one hydrocarbon gas and/or at least one liquid containing hydrocarbons, organometallic metal-complex, and/or element-organic compounds, evaporating organic material from the carbon-based material, nitrating the carbon-based material, and extracting carbon nano-onions from the nitrated carbon-based material.
