Beside steam reforming, methane pyrolysis is an alternative method for hydrogen production. ‘Turquoise’ with solid carbon formed in the process, contrary to ‘grey’ or ‘blue’ via where waste dioxide produced. Thermal conducted at higher temperatures, but catalytic decomposition of (CDM) a promising route sustainable CDM generally carried out over four types catalyst: nickel, carbon, noble metal and iron. The applied reactors can be fixed bed, fluidized plasma bed molten-metal reactors. Two main advantages are that (i) carbon-oxide free hydrogen, ideal fuel cell applications, (ii) by-product tailored into advanced morphology (e.g., nanofibers, nanotubes). aim this review reveal very recent research advances last two years achieved field prospective technology.
