Abstract

The invention discloses a catalyst using a TiO2-coated carbon nano tube composite material as a carrier and a preparation method thereof. The outer surface of a carbon nano tube is coated by TiO2 nanometer particles doped with an active component which is one or a plurality of of V2O5, MoO3, MnO2 and WoO3 and is 1-2 percent by weight of the catalyst. The catalyst is prepared by adopting a solvent hot method, has simple process, high yield and easy industrialized production and has excellent effects on denitrating smoke and removing dioxin-related persistent organic pollutants.

Description

technical field

[0001] The invention belongs to the field of catalysts, in particular to TiO 2 A catalyst coated with a carbon nanotube composite material as a carrier, a preparation method and an application thereof. Background technique

[0002] Some factories, such as waste incineration plants, metal smelters, coal-fired power plants, etc., will produce two main toxic substances nitrogen oxides (NO X ) and dioxins (Dioxins, also known as PCDD / DFs). The former will cause a variety of environmental problems including photochemical smog, acid rain, etc.; the latter is persistent organic pollutants, including polychlorinated dibenzodioxins (PCDDs) and polychlorinated dibenzofurans (PCDFs), these substances It accumulates in the human body through the food chain and causes great harm to the human body. All countries in the world have adopted laws and regulations and taken corresponding measures to strictly control them.

[0003] In order to reduce the emission of dioxins i...
