Abstract
The embodiments disclosed herein are directed to systems, methods, and devices for pyrolysis of methane in a microwave plasma for hydrogen production and structured carbon powder. Some methods are directed to producing a structured carbon powder using a microwave generated plasma comprising injecting a plasma gas comprising methane (CH4) into a liner, the liner in communication with a microwave waveguide; propagating microwaves through the microwave waveguide, the microwaves generated using a microwave generator; and generating a microwave plasma by contacting the plasma gas with the microwaves.
