Problems solved by technology

However, the operating temperature of the catalyst used to catalyze the oxidation of formaldehyde is usually much higher than room temperature, and it is difficult to meet the requirements of normal temperature and pressure and low energy consumption for indoor air purification. 2 O and CO 2 Only by using high-quality materials can we hope to realize the practical application of catalytic oxidation technology in the purification of formaldehyde in indoor air.

Description

technical field [0001] The invention relates to a purification material, in particular to a purification material for air adsorption. Background technique [0002] With the improvement of people's material and cultural living standards, interior decoration has become fashionable, and what follows is that the pollution of indoor air is becoming more and more serious. And for most people, regardless of work, study or life, people spend most of their time indoors. Although the harm of air pollution to human health has long been recognized by people, people's attention has gradually shifted to the harm of indoor air pollution to human health until the middle of the 20th century. There are many types of indoor air pollution, more extensive pollution sources, and complex influencing factors. The harm to human health is often more serious than outdoor air pollution. Indoor air quality research has become a new and important part in the field of environmental science, and has arou...
