What Are the Applications of Physical Adsorption in Nanotechnology?
Physical adsorption plays a critical role in various applications of nanotechnology:
1. Catalysis: Nanocatalysts rely on physical adsorption to increase the availability of reactants on their surfaces, enhancing reaction rates. 2. Environmental Remediation: Nanoadsorbents are used to remove pollutants from air and water due to their high adsorption capacities. 3. Sensors: Nanomaterials can adsorb specific molecules, causing changes in their electrical properties, which can be measured for sensor applications. 4. Drug Delivery: Nanocarriers can adsorb drug molecules on their surfaces, allowing for controlled release.
