Abstract
Hydrogen may be produced from natural gas (e.g., methane). For example, a method for producing hydrogen from natural gas may include: introducing natural gas to a reactor, wherein the reactor contains therein a catalyst, wherein the catalyst includes a high entropy alloy, and wherein the high entropy alloy has an entropy, S, such that S≥11.31 J K−1 mol−1; reacting the natural gas with the catalyst to form hydrogen gas and solid carbon; and separating the hydrogen gas from the solid carbon to produce a hydrogen stream comprising the hydrogen gas from the reactor.
