Analyte Adsorption and Distribution

2.5K
In certain chromatographic separations, solutes transfer between the mobile phase and the stationary phase via sorption, which typically refers to the process of adsorption. For many chromatographic systems, the sorption process often depends on the polarity of the compounds—an expression of the overall dipole moment within the molecule. During the separation process, there is competition between the solute and solvent for adsorption to the stationary phase. Highly polar compounds and...

Area of Science:

  • Materials Science
  • Computational Chemistry
  • Surface Science

Background:

  • Phosphorene, a 2D material, has potential applications in gas sensing and catalysis.
  • Carbon monoxide (CO) is a toxic gas requiring efficient removal and detection methods.
  • Metal decoration can modify the electronic and adsorption properties of 2D materials.

Purpose of the Study:

  • To investigate the stability of various metal-decorated phosphorene structures.
