Abstract

The invention discloses a catalyst for eliminating volatile organic compounds and a preparation method thereof. The catalyst is composed of a carrier, an active component and an auxiliary agent. The carrier is Nb2O5-Al2O3-CeVO4; the active component is Pt; and the auxiliary agent is MoO3; specifically, the Nb2O5-Al2O3-CeVO4 carrier is prepared by loading Nb2O5 and Al2O3 on CeVO4, the mass ratio ofNb2O5 to Al2O3 is 1:0.1-2, and the loading amount of Nb2O5-Al2O3 is 2-6wt% of CeVO4; the active component Pt and the auxiliary agent MoO3 are prepared by loading platinum acetylacetonate (II) and molybdenum acetylacetonate to the Nb2O5-Al2O3-CeVO4 carrier, the loading amount of Pt is 0.3wt%, and the mass ratio of Pt to MoO3 is 1:(0.5-3). The catalyst has very high reaction activity on benzene, toluene, ethyl acetate, acetone, n-hexanol and diethyl ether.

Description

technical field [0001] The invention relates to a chemical catalyst and a preparation method thereof, in particular to a catalyst for eliminating volatile organic compounds (VOCs) and a preparation method thereof. Background technique [0002] Volatile organic compounds (VOCs) are a class of common air pollutants with complex components and great harm to human body and environment. Volatile organic compounds are involved in petrochemical, dye, pharmaceutical, plastic, leather and other industries. These organic compounds are usually inhaled by the human body in the form of vapor, or enter the human body through skin contact, which are highly toxic to the human body and may cause cancer and other serious diseases. More importantly, viruses and germs can survive on such small particles, and when they attach to the particles in the atmosphere, they will spread diseases and pollute the atmospheric environment. Therefore, it is particularly important to strictly control the emi...
