Modified diatomite adsorption wallpaper and preparation method thereof
The invention discloses modified diatomite adsorption wallpaper and a preparation method thereof.The preparation method comprises the three steps of preparing modified diatomite, preparing a composite photocatalyst and preparing the modified diatomite adsorption wallpaper. The adsorption effect of a conventional diatomite catalyst is physical adsorption, and the adsorption capacity of the conventional diatomite catalyst to formaldehyde in air is not enough, so that the formaldehyde adsorption performance of the wallpaper is poor; the catalyst in the wallpaper is modified, so that chemical adsorption is increased, and adsorbed molecules are activated to accelerate a catalytic reaction; in the chemical adsorption process of formaldehyde, a reverse bond and a bonding track of the formaldehyde sequentially interact with electrons, and electrons are guided to enter and exit from a non-bonded orbit of the Lewis base and an unoccupied orbit of the Lewis acid, so that a synergistic chemical adsorption effect is generated, and formaldehyde in air can be better adsorbed on the catalyst.
本发明公开了一种改性硅藻土吸附壁纸及其制备方法，包括制备改性硅藻土、制备复合光催化剂以及制备改性硅藻土吸附壁纸3个步骤，常规的硅藻土催化剂的吸附效果是物理吸附，对空气中甲醛吸附力不够导致壁纸对甲醛吸附性能不佳，本发明对壁纸中的催化剂本身进行改性，从而增大化学吸附，并且激活吸附的分子以加速催化反应，在甲醛的化学吸附过程中，甲醛的反键和键合轨道依次与电子相互作用，并且引导电子进出路易斯碱的非键合轨道和路易斯酸的未占据轨道，从而产生协同化学吸附作用，使空气中的甲醛能更好的吸附在催化剂上。
