(a) a container having a closed bottom portion and an open top portion, suitable for housing a liquid hydrocarbon selected from at least one of methanol, and benzyl alcohol and mixtures thereof;

(b) a silicon wafer anode and a silicon wafer cathode each coated with catalytic nanoparticles of iron and nickel, wherein the anode and cathode are spaced apart and positioned in the bottom portion of the container as two electrodes in a plurality of electrodes in said container;

(c) a magnetic stirrer for agitating the liquid hydrocarbon in the container; and

(d) a power supply with an ammeter and a voltmeter connected between the anode and the cathode for imposing a direct current potential of approximately 1000 volts between the two electrodes and providing a current density of approximately 12 miliamps per square centimeter between the two electrodes for a time sufficient that carbon nanoparticles are deposited on said the two electrodes, wherein each of the carbon nanoparticles includes:

a nanotube produced from the organic solution under ambient conditions having a diameter ranging from approximately 50 nm to approximately 100 nm and a length ranging from approximately 2 nm to approximately 50 μm.
