With the increasing serious global environmental problems, the research and development and application of environmentally friendly materials have become a hot topic in the field of science and technology today. As a new type of environmentally friendly catalyst, the post-matured catalyst TAP (Thermally Activated Persulfate) has attracted much attention. This article will explore in-depth the basic principles, product parameters, application fields and their specific role in environmentally friendly materials.
Post-ripening catalyst TAP is a catalyst that generates strong oxidative free radicals by thermally activating persulfate. These free radicals can effectively degrade organic pollutants and convert them into harmless substances.
The working principle of TAP catalyst is mainly based on the thermal activation of persulfates to produce sulfate radicals (SO4•-) and hydroxyl radicals (•OH). These free radicals have extremely strong oxidation capabilities and can rapidly degrade organic pollutants. The specific reaction process is as follows:
Thermal activation process:
[
S_2O_8^{2-} xrightarrow{Delta} 2SO_4^{•-}
]
The persulfate is decomposed into sulfate radicals under heating.
Free Radical Reaction:
[
SO_4^{•-} + H_2O rightarrow SO_4^{2-} + •OH + H^+
]
The sulfate radical reacts with water to form hydroxyl radicals.
Contaminant Degradation:
[
R-H + SO_4^{•-} rightarrow R• + HSO_4^-
]
Free radicals react with organic pollutants to degrade them into small molecules or harmless substances.

In the future, one of the research and development directions of TAP catalysts is to improve its catalytic efficiency, and to improve the yield and reaction rate of free radicals by optimizing the structure and composition of the catalyst, thereby further improving the degradation efficiency and environmental performance of the material.
There is still a lot of room for expansion in the application field of TAP catalysts. In the future, it can further explore its application in more environmentally friendly materials, such as environmentally friendly paper, environmentally friendly rubber, etc., to provide more possibilities for the research and development of environmentally friendly materials.
At present, the production cost of TAP catalysts is relatively high. In the future, it can reduce its production costs by optimizing production processes and finding cheaper raw materials, so that it can be applied in a wider range of fields.
The stability of TAP catalyst at high temperatures needs to be improved. In the future, it can enhance its stability at high temperatures and extend its service life by improving the formulation and preparation process of the catalyst.
