The main application and market demand of active copper oxide were introduced. The main test methods used for the activity of the product and the standardized and unified test methods for the activity given in the newly promulgated industrial standard of the product in China were described. The research status of the process, technical characteristics and product quality of the main preparation methods of active copper oxide, such as direct precipitation method, low temperature oxidation wet decomposition method, copper dissolution-denitrification method and complex precipitation method, were reviewed. The main advantages and disadvantages of each preparation method were analyzed. It is believed that the development trend of active copper oxide and its preparation method is to conduct in-depth research on the existing copper dissolution-ammonia distillation process, and put forward effective improvement measures to further improve the quality of products such as activity and fluidity, and improve their application performance.
