A Triazolate-Based MOF with Amino-Induced Triazolate Reorientation Enabling Pore-Size Regulation for CO2/CH4 Separation

Key Points

• The research aims to explore how amino functionalization affects pore size regulation in a triazolate-based MOF for improved gas separation.
• Synthesis of a triazolate-based MOF with amino groups.
• Characterization of pore structure and size using microscopy techniques.
• Evaluation of gas separation performance for CO2 and CH4.
• Induced pore contraction due to amino functionalization restrained CH4 diffusion.
• CO2 permeability was effectively maintained despite CH4 suppression.
• Achieved angstrom-level precision in pore size adjustment.
