Abstract
A method of making at least one nanographene layer is disclosed herein. The method includes selecting X hydrocarbon precursor and Y hydrogen gas (H) such that a ratio of X/Y ranges from 0.5 to 1, the hydrocarbon precursor including at least one of CH, CHor CH. The method further includes submitting the hydrocarbon precursor to chemical vapor deposition using the hydrogen gas and argon gas (Ar). As a result, i) the hydrocarbon precursor reacts with the hydrogen gas and argon gas (Ar) according to the following reaction:X hydrocarbon precursor+YH+ZAr→2X graphene+(Y+2X)H+ZAr,where Z ranges from 5*(X+Y) to 10*(X+Y), and ii) the hydrocarbon precursor decomposes and self-assembles to form the at least one nanographene layer.
