Synthesis of Al_2O_3-silica fibers supported on a V_2O_5-K_2SO_4 catalyst used for soot combustion
Source abstract
Abstract
An A1_2O_3-silica fiber support was prepared by first impregnating a Al(NO_3)_3 solution on a silica fiber mat on which sacrificial carbon nanofibers had been formed by chemical-vapor deposition,followed by burning in air.The support was further impregnated with a solution containing NH_4VO_3 and K_2SO_4 to prepare the Al_2O_3-silica fiber supported V_2O_5-K_2SO_4 catalyst.The catalyst can greatly decrease the combustion temperature of soot by around 200 ℃,which is promising for decreasing soot emission in diesel-powered vehicles.
