Overview

NMR relaxation analysis reveals microphase separation in silica pores, highlighting the role of surface chemistry.

Key Points

  • Competitive adsorption processes in mesoporous silicas show significant differences based on pore size.
  • NMR relaxation analysis demonstrated a strong microphase separation in larger pore silicas (≥20 nm).
  • Surface hydroxyl density significantly influences the adsorption and phase behavior of confined fluids.
  • Modifications in silica surface chemistry affect competitive adsorption properties and microphase behavior.
