What are the Challenges Associated with Physical Adsorption in Nanotechnology?
Despite its advantages, physical adsorption using nanomaterials also faces several challenges:
1. Aggregation: Nanoparticles tend to aggregate, reducing their effective surface area and adsorption efficiency. 2. Desorption: Ensuring the complete desorption of adsorbates can be challenging, especially for applications requiring high purity. 3. Stability: Nanomaterials can be unstable under certain conditions, leading to degradation and loss of adsorption capacity. 4. Cost: The production and functionalization of nanomaterials can be expensive, limiting their widespread use.
