CH4TPD analyses were conducted to measure methane adsorptionreduced NiE/MA and Ni/MA catalysts The amount of adsor!ed CH4 oncatalysts was calculated from the CH4TPD profiles "t was re#ealed thaNiE/MA catalyst e$hi!ited lar%er amount of adsor!ed CH4 than the re

catalyst This is !ecause the reduced NiE/MA catalyst retained lar%er amohydro%en&!indin% sites than the reduced Ni/MA catalyst
