Description

technical field [0001] The invention relates to the field of functional coatings, in particular to a cerium-aluminum co-doped zinc oxide negative ion coating and a preparation method and application thereof. Background technique [0002] At present, the ways of artificially generating negative ions mainly include water molecule separation and release device separation and so on. In functional coatings, negative ion coatings are an advanced environmentally friendly functional material. Negative ion coating: unique formula, excellent performance, green ecology, environment-friendly, with forest function. It is widely used in the painting of homes, schools, hospitals, high-end apartments and catering operations. However, negative ion coatings are still in the initial development stage, and the amount of negative ions released is small. As a new nanomaterial, cerium-aluminum co-doped zinc oxide is also a catalyst. It uses photocatalysis to carry out chemical reactions and help...
