Hydrogen production by steam reforming of liquefied natural gas (LNG) over mesoporous Ni-Al2O3 aerogel catalyst prepared by a single-step epoxide-driven sol-gel method

► Hydrogen was produced by steam reforming of liquefied natural gas (LNG). ► A Ni-Al2O3 catalyst was prepared by an epoxide-driven sol-gel method (NA-ES). ► A Ni-Al2O3 catalyst was prepared by an alkoxide-based sol-gel method (NA-AS). ► NA-ES showed higher LNG conversion and hydrogen yield than NA-AS.
