Development of robust catalytic materials to meet our daily energy needs is arguably the most critical scientific and engineering challenge. Methane (CH4), as the primary component of natural gas, methane clathrates, and shale gas, is poised to become the most crucial hydrocarbon feedstock for fuel and chemical synthesis, providing an economical alternative to the declining petroleum reserves. Despite the vast availability of methane, it requires a complex infrastructure for secure transportation, storage, and distribution, limiting efficient usage of the natural resources. In addition, methane is the second most abundant greenhouse gas with a potential to contribute to global warming approximately 25 times greater than carbon dioxide (CO2) over the next one hundred year. Therefore, there is an urgent need to discover low-carbon footprint methods to selectively convert methane to transportable high-energy-density liquid fuels and value-added chemical feedstocks.
