US 12,698,400 B2 · Carbon-based nanomaterial composition and methods of forming the same from a gas mixture that includes acetylene gas

Abstract

The present disclosure relates to a carbon-based nanomaterial composition that may be formed from a gas mixture. The gas mixture may include acetylene gas at a molar ratio AGmol/GMmol of at least about 0.55 and not greater than about 0.99, oxygen gas at a molar ratio OGmol/GMmol of at least about 0.01 and not greater than about 0.75, and hydrogen gas at a molar ratio HGmol/GMmol of at least about 0.05 and not greater than about 0.90. The carbon-based nanomaterial composition may have a carbon hybridization ratio Psp3/Psp2 of at least about 0.0 and not greater than about 5.0, where Psp3 is the percent of carbon within the carbon-based nanomaterial composition having a sp3 hybridization and Psp2 is the percent of carbon within the carbon-based nanomaterial composition having a sp2 hybridization.
