Problems solved by technology

People often use physical adsorption or chemical decomposition to purify the air. The usual physical adsorption materials mainly include activated carbon. Due to its large specific surface area, activated carbon can easily absorb harmful gases in the air, but its adsorption capacity is limited, and only Adsorption does not decompose harmful substances; in the research of chemical decomposition, the characteristics of limited decomposition amount and slow decomposition speed are often referred to, and some additional conditions such as light and PH value are required, and the purification performance is not sustainable. For example, the patent CN1021101008A discloses Soaking inorganic adsorption materials in 5-20% inorganic oxidant aqueous solution for 18-36 hours and then drying can improve the purification effect; but only by soaking to load oxidant, the load is not sufficient and firm, and the purification performance shown cannot last
