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 CeO(2) 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.
