Problems solved by technology

Each of these technologies has its own advantages. For example, photocatalytic technology can degrade indoor formaldehyde, but because it is indoors, there is less light that can produce photocatalytic action, and the effect is limited; using plants to purify formaldehyde is a widely used method by the public. However, formaldehyde also has a serious impact on plants. Improper handling will lead to plant death and even accelerate the release of formaldehyde

Description

technical field [0001] The invention relates to the field of graphene materials, in particular to a method for preparing a graphene / activated carbon composite material adsorption package. Background technique [0002] Formaldehyde is a systemic poison and was identified as a Class 1 carcinogen in 2006. Formaldehyde, which is harmful to the human body in daily life, can be said to be everywhere. The items involved include furniture, wooden floors, cars, etc. At present, various methods have been adopted at home and abroad to control indoor formaldehyde pollution. These purification technologies are summarized as follows: adsorption technology, photocatalysis technology, negative air ion technology, And technology, ozone oxidation technology, biotechnology, room temperature catalytic oxidation technology, etc. Each of these technologies has its own advantages. For example, photocatalytic technology can degrade indoor formaldehyde, but because it is indoors, there is less lig...
