Working Principle
Work principle basis of the thermosensitive catalyst SA-102Reversible changes in the reactive groups in their molecular structure over a specific temperature range. When the temperature rises to its catalytic temperature range, the molecular structure of SA-102 changes, exposing active sites, thereby catalyzing a specific chemical reaction. When the temperature drops, the molecular structure returns to its original state and the catalytic activity disappears.
1. Temperature response mechanism
The temperature response mechanism of SA-102 depends mainly on the thermosensitive groups in its molecular structure. These groups undergo conformational changes at specific temperatures, thereby changing catalytic activity. Specifically, when the temperature increases, the heat-sensitive group stretches, exposing the active site; when the temperature decreases, the heat-sensitive group shrinks, and the active site is masked.
2. Catalytic reaction mechanism
The catalytic reaction mechanism of SA-102 involves multiple steps, including substrate adsorption, active site exposure, reaction progression and product desorption. The specific steps are as follows:
- Substrate Adsorption: Substrate molecules are adsorbed on the surface of SA-102.
- Active site exposure: The temperature rises, the heat-sensitive group stretches, and the active site is exposed.
- Reaction proceeds: The substrate molecule undergoes chemical reaction at the active site.
- Product Desorption: The reaction product is desorbed from the surface of SA-102.
