Mesoporous Ni/Ce1−xNixO2−y heterostructure as an efficient catalyst for converting greenhouse gas to H2 and syngas

摘要: It has been a great challenge to develop an efficient and stable catalyst for dry reforming of methane with carbon dioxide. A new was synthesized the catalytically active component in both lattice on surface mesoporous support. remarkable improvement catalytic performance Ni nanocrystals assembled inside pore channels mesostructured Ni-doped ceria observed. The initial activity long-term stability sample substantially surpassed that samples without intermixed oxide and/or nonporous architecture, even though latter more available. Such effect concerning collaborative function stemming from mesostructure solid solution rarely reported previously catalysis involving CeO2. We believe this finding might be very generic character extended lots similar fields. is expected results here can spur experimental theoretical investigation promote fundamental comprehension host–guest or metal–oxide interplay CeO2-based composite materials.
