Physisorption

Physisorption is a process where molecules stick to a surface through weak, temporary forces, like van der Waals interactions. This occurs without any chemical changes to the molecules or the surface. It typically happens at low temperatures and involves physical attraction, meaning the molecules can easily detach from the surface. Physisorption is important in various applications, including catalysis, gas storage, and sensor technology, as it allows for reversible interactions, enabling materials to capture and release substances efficiently.
