Abstract

The invention relates to a Mn (VO3) 2 / V2O5 catalyst and a preparation method and application thereof, and the preparation method comprises the following steps: (1) dissolving a vanadium salt in a polyhydroxy compound aqueous solution, adding a manganese salt, uniformly mixing to obtain a precursor solution, then carrying out a hydrothermal reaction, and collecting a precipitation product after the reaction is finished; and (2) cleaning the precipitation product for multiple times, drying, carrying out pre-oxidation treatment in an oxidation atmosphere, and then carrying out carbonization treatment in a nitrogen atmosphere to prepare the Mn (VO3) 2 / V2O5 catalyst. The second metal is doped in the vanadium-based catalyst to form the doped composite catalyst, the doped composite catalyst has good catalytic oxidation activity, the catalytic oxidation efficiency of the catalyst on CBs can be improved, and the reaction temperature can be reduced.

Description

A Mn(VO 3 ) 2 / V 2 O 5 Catalyst and its preparation method and application technical field The present invention relates to inorganic catalyst technical field, be specifically related to a kind of Mn(VO 3 ) 2 / V 2 O 5 Catalyst and its preparation law and application. Background technique Chlorobenzene volatile organic compounds (CBs) are harmful to the environment and human health, and excessive discharge can cause secondary organic gas Increases in sols (SOA), peroxyacetyl nitrate (PAN) and tropospheric ozone, which are also major contributors to the greenhouse gas effect Contributor. As a result, relevant regulations on CBs emissions have become progressively improved and more stringent, developing a high-performance, low-cost The current CBs removal technology has urgently become the main problem that scholars need to overcome. Generally the treatment method for CBs is catalytic combustion method, and this method is in the presen...
