Description

technical field

[0001] The invention belongs to the field of material chemistry, and in particular relates to a catalytic oxidation application of a sulfaquinoxaline cobalt compound. Background technique

[0002] Catalytic oxidation reaction is one of the most important reactions in chemical industry and medicine field. Most of the oxidants used in early catalytic oxidation reactions were various inorganic compound oxidants, such as potassium permanganate, potassium dichromate, etc. These oxidants seriously polluted the environment. As environmental issues are getting more and more attention, environmentally friendly green oxidants (such as oxygen, hydrogen peroxide, ozone, etc.) are favored by people and have become a research hotspot in oxidation reactions. However, this kind of oxidizing agent has disadvantages such as weak oxidizing ability, uncertain oxidizing performance, and complex reaction conditions. Studies have found that under the action of some coordination c...
