The formaldehyde removal efficiency reaches 91%, and the durability reaches 86.7%; and the toluene removal efficiency reaches 64%, and the durability reaches 54%.

Description

technical field [0001] The invention relates to a aldehyde-removing antibacterial coating based on a titanium-based metal organic framework material and a preparation method thereof. Background technique [0002] With the development of social economy and the improvement of people's living standards, everyone's awareness of health and environmental protection is gradually increasing, and the requirements for the safety of the living environment are also getting higher and higher. In the indoor environment, volatile organic compounds (VOCs) are the main cause of indoor air pollution, and among various VOCs, formaldehyde (HCHO) is the main harmful indoor air pollutant (Build.Environ.,2017,117,118- 126), the presence of formaldehyde is a major hazard to human health, and long-term exposure to formaldehyde may cause serious health problems, such as skin and eye irritation, neurodegenerative diseases, leukemia, pneumonia, brain tumors, and even nasopharyngeal cancer (Appl .Catal...
