Aspects of the invention are associated with the discovery of processes for converting methane (CH4), present in a methane-containing feed that may be obtained from a variety of sources such as natural gas, to higher hydrocarbons (e.g., C2+ hydrocarbons) such as C2 hydrocarbons (e.g., ethane, ethylene, and acetylene) and aromatic hydrocarbons (e.g., benzene, one or more C1- or C2-substituted benzenes, and / or one or more fused ring aromatic hydrocarbons).

The inventive concepts disclosed relate to the production of green and blue hydrogen from hydrocarbons using visible light (from a laser, lamp or sun) and defect-engineered boron-rich photocatalysts. We demonstrate that the environment of the B atoms in the lattice can be tuned to favor the dehydrogenation of desired hydrocarbons on reaction sites under visible light. In addition to the hydrogen produced in gas form, carbon atoms are captured by the catalyst and form structures of potential higher value for future applications. Further study of the dark carbonaceous product revealed a graphitic aspect of the material. These findings highlight a new functionality of 2D materials for visible light-assisted capture and conversion of hydrocarbons, with great potential for green hydrogen production—i.e, hydrogen produced from renewable energy and without the release of CO or CO2.
