nitrogen adsorption
Nitrogen adsorption is a scientific technique used to measure the surface area and porosity of materials, commonly in the study of catalysts, adsorbents, and porous materials. In this process, nitrogen gas is exposed to a material at low temperatures. As the gas molecules adhere to the surface, researchers can analyze how much nitrogen is absorbed. By calculating the amount of nitrogen that fills the pores, scientists can determine the structure and properties of the material. This information is essential for applications in environmental science, gas storage, and material development.

Nitrogen adsorption is a method used to measure the surface area and porosity of materials, particularly in research and industrial applications. By exposing a sample to nitrogen gas at specific temperatures and pressures, scientists observe how much nitrogen the material can "吸附" (adhere) over its surface. The amount of gas captured helps determine the size and number of pores in the material, which is crucial for applications like catalysts, adsorbents, and filters. This technique provides valuable insights into how a material can interact with other substances in various practical uses.
