Gravity-Driven Multiple Collision-Enhanced Catalytic Soot Combustion over a Space-Open Array Catalyst Consisting of Ultrathin Ceria Nanobelts

Gravity-Driven Multiple Collision-Enhanced Catalytic Soot Combustion over a Space-Open Array Catalyst Consisting of Ultrathin Ceria Nanobelts

More than 122 times higher contact efficiency between soot and catalysts is achieved over the as‐prepared CeO2 nanobelt array catalysts as compared with the powder nanoparticle catalyst. A novel gravity‐driven multiple collision‐enhanced soot combustion mechanism is proposed for the first time....
