Description

technical field [0001] The invention belongs to the technical field of electrochemical catalysis, and in particular relates to a polyacid-based Ag(I) coordination polymer and a preparation method and application thereof. Background technique [0002] Coordination polymers have achieved remarkable results in the fields of gas storage and separation, heterogeneous catalysis, magnetism, and sensing. However, the functional design and development of such materials is far from enough, such as in Electrocatalysis technology field. Hydrogen peroxide aqueous solution, commonly known as hydrogen peroxide, is a widely used traditional inorganic chemical product. It is often used for disinfection of medical wounds and food disinfection. However, due to its slow decomposition, the vapor or mist inhaled from this product is strongly irritating to the respiratory tract and eyes. Direct contact with liquids can cause irreversible damage and even blindness. There are many methods for cata...
