Background technique
Microbes pollutant and contaminants of chemical origin in air pollution, generally use absorption, photocatalysis, anion,
The methods of plasma, ozone are purified.In these methods, with high-concentrated ozone purification side
Method is most effective, 2.07 volts of the standard electrode potential of ozone, chemical reaction rate constant 101~102L/ (mols),
Ozone kills mould (one kind of more difficult killing in microbes pollution) in the gas phase, and the time needs 100min, and ozone purification still has
Shortcoming, and ozone is harmful to the human body, and air sterilizing purification indoors is unable to man-computer symbiosis.However OH have it is stronger
Oxidability (2.80 volts of standard electrode potential), it is almost suitable with the oxidability of simple substance fluoride (2.87 volts), is a kind of strong
Oxidation material.The reaction of OH belongs to radical reaction simultaneously, has very high chemical reaction rate 107~109L/(mol·
S), 7 orders of magnitude higher than ozone.Its chemical time is less than 1s, 1~10s of biochemical reaction time.But due to the service life pole OH
Short (10ns or so) is controlled so OH preparation and pollution control need to be carried out in the same time while generating OH
Reason, that is must realize in-situ regeneration high concentration gaseous phase free radical, or scale prepare gaseous phase free radical OH,
ClO2、·HO2, O isoreactivity particle.
Silicon dioxide meter has extremely strong affinity in face of water, and hydrone can irreversibly or reversibly be adsorbed on surface
On, so silica surface is usually to be covered with by one layer of OH (hydroxyl) and absorption water.The former is bonded to surface Si original
Hydroxyl on son, that is, chemical absorbed water；The latter is the water for being adsorbed on surface molecular, that is, the water of physical absorption.Big
On the basis of measuring experimental fact, by us, observation and deep Theory Thinking, this characteristic of silica help us real for a long time
The dream that scale prepares the gaseous phase free radicals such as hydroxyl radical free radical is showed.When silicon dioxide carried Stable chlorine dioxide solution, and pass through
After 85 DEG C or less dryings, under no light, without heating state, ClO2Silica surface mechanical water (a small amount of) is set to have ionization water
Solve H2O → H++OH-, to there is ClO2+H2O→HClO2+HClO3Slow hydrolysis it is outer, there is also the nonionics of chemical absorbed water
Hydrolysis：
To there is ClO2+·H→HClO2
Overall reaction is ClO2+H2O→HClO2+·OH
In addition, there are also 2OH → H2O2
And OH+H2O2→·HO2+H2O
Above-mentioned non-ionic hydrolysis (free radical pattern) is not significant under normal circumstances, but is having substrate to react or have
It can be greatly accelerated when being physically or chemically catalyzed, to there is a large amount of OH to generate.
·O+H2O→2·OH
·ClO+H2O+O2→HClO2+·HO2
3·O→O3
O2+·HO2→·OH+2O2
O3+H20→2·OH+O2
Since also there is the surface hydroxyl generated because adsorbing water on active aluminum oxide surface, so also there is above-mentioned titanium dioxide
The characteristic of silicon.
It is mark that high-level oxidation technology, which is to generate OH, however the method that gaseous state generates OH at present, such as patent
201010567135.8 requiring huge optional equipment and at high cost with 201310700249.9, it is difficult large-scale industry and answers
With.
