Catalyst for thermally stable degradation of vocs, preparation method thereof and use thereof

Abstract

The present application discloses a catalyst for thermally stably degradation of VOCs, a preparation method thereof and a use thereof. The catalyst includes: a substrate, and an auxiliary agent and an active component which are on the substrate. The auxiliary agent includes a first auxiliary agent and a second auxiliary agent; the first auxiliary agent includes a cobalt-containing auxiliary agent and/or an iron-containing auxiliary agent; and the second auxiliary agent includes an aluminum-based auxiliary agent. The combination of specific first and second auxiliary agents is introduced into the catalyst of the present application, so that oxygen molecules can be quickly adsorbed and activated during the catalytic combustion process of VOCs with forming a catalytic synergy center with the active component, thereby improving the removal efficiency for VOCs and facilitating the long-term stable operation of the catalyst under harsh conditions such as high-temperature and high-humidity conditions.
