Probing the differential methane decomposition behaviors of n-Ni/SiO2, n-Fe/SiO2 and n-Co/SiO2 catalysts prepared by co-precipitation cum modified Stöber method

What is it about?

n-Ni/SiO2, n-Fe/SiO2 and n-Co/SiO2 nano-catalysts were prepared by co-precipitation cum modified Stöber method and applied for thermocatalytic decomposition of methane in order to investigate their thermal stability and activity to produce greenhouse gas free hydrogen and nano-carbon. The mean particles sizes of the produced nano-catalysts obtained from BET analysis are 32.19 nm, 30.26 nm and 49.92 nm, respectively. Temperature programmed methane decomposition were conducted as a preliminary catalytic examination and further isothermal analyses were performed at 700 °C, 600 °C and 500 °C.
