Method for preparing catalyst with thermal-instability material carrier by using low-temperature plasma and application of catalyst

The invention relates to a method for preparing a catalyst with thermal-instability material carrier by using low-temperature plasma and an application of the catalyst, and the method comprises the following steps: impregnating thermal-instability material with metal salt; directly loading the thermal-instability material carrying the metal salt into a plasma discharger; vacuumizing the interior of the plasma discharger, then introducing plasma discharge gas, maintaining the pressure of the gas at 30-200Pa, utilizing a high-voltage power supply to apply 200-5000V direct current or alternatingcurrent to two ends of an electrode for enabling the discharge gas to discharge, and reducing or decomposing the metal salt with the formed plasma for 5-120 minutes without damaging the structure of the thermal-instability material so as to obtain the required catalyst finally. The catalyst with a thermal-instability material carrier, which is prepared from plasma, has the advantages of large output, good catalytic activity and the like, and the particle size of active components can be controlled easily. The adverse thermal effect and the series damages to the structure of the material with the thermal instability under high temperature can be avoided, so that the active components are fine and small in particles, uniform in distribution, high in purity and good in dispersivity.
