Supported catalyzer for low-temperature catalytic combustion of VOCs and method for preparing supported catalyzer for low-temperature catalytic combustion of VOCs

The invention discloses a supported mesoporous carbon catalyzer RTCC-1 for low-temperature catalytic combustion of VOCs and a method for preparing the supported mesoporous carbon catalyzer RTCC-1. Due to the fact that the TSC-1 mesoporous carbon material which has the unique physicochemical property serves as the carrier of the catalyzer, the disadvantages of a traditional catalyzer for catalytic combustion that the active metal load is high and the cost is high are eliminated. The active components of the supported catalyzer, for low-temperature catalytic combustion, prepared with the carrier include one of the precious metal Pd and the precious metal Pt and one or more of copper oxide, cerium oxide, zirconium oxide, silicon oxide and aluminium oxide. The catalyzer has extremely high room-temperature catalytic combustion activity and enables complete catalytic combustion of the VOCs such as formaldehyde, methylbenzene and benzene to be achieved at room temperature or at even lower temperature.
