Daily application scenarios of copper oxide

Copper oxide catalyst is widely used in daily life, it is mainly used in the following fields:
Organic synthesis reaction
In the oxidation reaction of alcohols, copper oxide can oxidize primary alcohols to aldehydes and secondary alcohols to ketones. For example, when preparing benzaldehyde in the laboratory, copper oxide can be used as a catalyst to efficiently convert benzyl alcohol to benzaldehyde under relatively mild conditions. In some hydrogenation reactions, the composite catalyst composed of copper oxide and other metals can effectively catalyze the hydrogenation of unsaturated compounds, such as the hydrogenation of olefin to alkanes. In addition, copper oxide can also be used to catalyze transesterification reactions, which helps to improve the reaction rate and product selectivity in the production of biodiesel.
Petroleum desulfurization
Copper oxide can be used as a desulfurizer, react with sulfur compounds in petroleum to generate copper sulfide precipitates that are easy to separate and treat, thereby reducing the sulfur content in petroleum products, reducing the emission of sulfur dioxide during combustion, and improving the quality and environmental performance of petroleum products.
Energy field
Fuel cells: In some types of fuel cells, copper oxide can be used as a catalyst or catalyst carrier to promote the oxidation reaction of fuel and the reduction reaction of oxygen, improving the performance and efficiency of fuel cells, such as in direct methanol fuel cells, copper oxide can catalyze the oxidation reaction of methanol, making it more efficient to convert into electrical energy.
Hydrogen production reaction: In some thermal-chemical hydrogen production processes, copper oxide can be used as a catalyst to participate in the reaction, promoting the decomposition of water or the reforming reaction of other hydrogen-containing compounds, and improving the production and reaction efficiency of hydrogen.
Environmental field
Automobile exhaust purification: The composite catalyst composed of copper oxide and other metal oxides can effectively catalyze the conversion reaction of pollutants such as carbon monoxide, hydrocarbons and nitrogen oxides in automobile exhaust, converting them into harmless carbon dioxide, water and nitrogen, etc., reducing the pollution of automobile exhaust to the environment.
Industrial waste gas treatment: In the exhaust gas produced in some industrial production processes, such as the exhaust gas containing sulfur dioxide, nitrogen oxides, volatile organic compounds and other pollutants, copper oxide catalysts can participate in catalytic oxidation, reduction or decomposition reactions, and convert these pollutants into harmless substances or compounds that are easy to handle, so as to achieve the purification of waste gas and discharge standards.
