Explore the role of post-mature catalyst TAP in environmentally friendly materials

Introduction

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.

1. Basic principles of post-ripening catalyst TAP

1.1 Definition of TAP catalyst

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.

1.2 Working principle of TAP catalyst

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:

1. Thermal activation process:
   [
   S_2O_8^{2-} xrightarrow{Delta} 2SO_4^{•-}
   ]
   The persulfate is decomposed into sulfate radicals under heating.

2. Free Radical Reaction:
   [
   SO_4^{•-} + H_2O rightarrow SO_4^{2-} + •OH + H^+
   ]
   The sulfate radical reacts with water to form hydroxyl radicals.

3. 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.
