Nickel Nanoparticles Supported on Nonreducible Mesoporous Materials: Effects of Framework Types on the Catalytic Decomposition of Methane

摘要

Hydrogen is viewed as a key green energy source by the chemical and petrochemical industries because energic use of hydrogen does not generate greenhouse gas emissions.As a result,many researches have explored methods of generating hydrogen in an economical way.Methane is the main constituent of biogas and natural gas,and have the hydrogen/carbon ratio of four,which is higher than that of any other hydrocarbon.Many processes have been devised to extract hydrogen from methane,including steam reforming of methane,4 catalytic decomposition of methane(CDM),5 and partial oxidation of methane6;however,CDM is considered to have the greatest potential in terms of its low CO2 emissions.
