Attapulgite clay loaded copper oxide catalyst and its application in carbon monoxide oxidation

Abstract

The invention relates to a preparation method of a natural attapulgite clay loading cupric oxide nanometer catalyst, which is applied for catalyzing CO for low-temperature oxidation. A deposition-settlement method is adopted to prepare the nanometer catalyst with high ratio surface area by loading the cupric oxide nanometer particles on the natural attapulgite clay carrier. In the preparation process, the loading quantity of the cupric oxide is easily controlled, the operation is simple and the raw material is easy to gain. The prepared catalyst has high activation performance of catalyzing the CO low-temperature oxidation and has greater industrial application significance.

Description

Attapulgite clay-supported copper oxide catalyst and its application in carbon monoxide oxidation technical field The invention relates to a natural attapulgite clay-supported copper oxide catalyst and a preparation method thereof, which is applied to the catalytic oxidation of carbon monoxide, and belongs to the field of solid catalytic materials. Background technique As one of the important environmental pollutants, the existence of carbon monoxide seriously affects human health, and the elimination of carbon monoxide is of great significance to the environment and industrial production, such as gas purification, tobacco harm reduction, safety assurance, etc., and catalytic oxidation It is a simple and effective method. Although traditional noble metal catalysts have excellent catalytic activity for low-temperature oxidation of CO, their wide application in industry is limited due to their high price, low content in nature, and susceptibility to sulfur poisoning. As a c...
