| 英文摘要 | Identification of catalytically active species and reaction pathway in catalytic solid (catalyst)-solid (reactant) reactions is a nontrivial task as exemplified in diesel soot oxidation (combustion), the technology for control of diesel particulate emissions. a physical contact between catalytically active species and solid soot is usually deemed necessary. herein, thermally-stable hollandite-type alpha-mno2 (kxmn8o16) nanorod catalysts have been synthesized with one-dimensional tunnel structures partially filled with relatively mobile k cations. these tunnel-confined quasi free k cations are revealed to be responsible for the catalytic soot oxidation activity, proving that physical contact between soot and k cations is unnecessary for solid-solid reaction. a novel catalyst, kyti8o16 has been successfully designed to boost the catalytic activity in tio2 toward soot oxidation by engineering a k-contained hollandite-type isostructure. |
