Researchers develop novel plasma process for scalable graphene oxide production

The approach is based on a non-thermal atmospheric nano-second pulsed plasma (NSPP) process, in which methane is decomposed at or near a water surface that acts as the substrate. Unlike traditional chemical vapor deposition (CVD), which requires high temperatures, reduced pressures, and inert gases, this system operates under ambient conditions without additional gas inputs. The plasma generates a highly reactive environment of radicals and ions, enabling methane to break down and reorganize into graphene oxide sheets directly at the methane-water interface.

Researchers from Texas A&M University and LTEOIL recently demonstrated a scalable, plasma-based route for producing graphene oxide (GO) directly from methane, combining atmospheric-pressure processing with a liquid-phase growth interface to overcome key limitations of conventional synthesis methods.The approach is based on a non-thermal atmospheric nano-second pulsed plasma (NSPP) process, in which methane is decomposed at or near a water surface that acts as the substrate.
