Problems solved by technology

Traditional photocatalysts mostly use inorganic semiconductor materials. Such materials are composed of inorganic salts, and their structure and performance are not easy to control. Most of the catalysts absorb wavelengths mainly in the ultraviolet region, so artificial light sources must be used, which consume a lot of power.

Description

technical field [0001] The invention relates to the preparation of a porous organic polymer catalyst based on triazine and triphenylamine and its application in the photocatalytic conversion of carbon dioxide to carbon monoxide, providing potential applications for the utilization of carbon dioxide in industrial waste gas. Background technique [0002] Climate change caused by greenhouse gases mainly carbon dioxide has seriously endangered the living environment of human beings. my country has included the carbon dioxide emission reduction target as a binding indicator into the medium and long-term planning for national economic and social development. Although my country's current energy structure has tended to be diversified, the dominant position of coal is still unshakable. Carbon dioxide emissions caused by coal burning have become the main source of carbon dioxide emissions in my country, so it is particularly important to establish a sound carbon dioxide emission red...
