摘要: Abstract CO 2 reforming of ethanol has been investigated for hydrogen production by reacting , which is a greenhouse gas, with ethanol, renewable energy source, over Rh/Ce-SBA-15 catalysts. A series catalysts have prepared using Ce-SBA-15 supports different Ce/Si molar ratio synthesized direct synthesis method. The characterized TEM, FESEM, XRD, BET, TPR, TPD and XPS. All samples show high surface area mesoporous structure at (= 0–1/5), whereas the destroyed (= 1/1). catalytic tests that significant influence on rate product selectivity. optimal highest found to be 1/20. increase activity 1%Rh/Ce-SBA-15 from Ce/Si = 0 Ce/Si = 1/20 attributed amount Ce incorporated into SBA-15 framework, resulting in enhancement mobility oxygen species. (Ce/Si = 1/20) most active, selective stable catalyst syngas or hydrogen.
