Ordered Mesoporous Carbons As Highly Active Catalysts For Hydrogen Production By Ch_4 Decomposition

摘要

Ordered mesoporous carbons have been applied, for the first time, as catalysts for hydrogen production via methane decomposition, showing higher and more stable activity than commercial carbonaceous catalysts.rnSince the hydrogen energy transition was recognized worldwide as one of the most promising alternatives to carbon-based fuels, great efforts have been dedicated by the scientific community to both production and storage of hydrogen. A variety of routes to produce hydrogen, such as photocatalytic water splitting, are being explored. Thus, catalytic methane decomposition is considered as one of the most promising methods in the short-term since no CO/CO_2 emissions are produced. Moreover, the carbon generated in this process as by-product can be commercialized, thus improving its overall economy.
