1. Applications of Monometallic MOFs in Catalysis and Environmental Fields By Nguyễn Thảo

2. Catalytic Roles of Monometallic MOFs • Provide active metal centers for catalytic reactions. • Enable uniform dispersion of active sites. • Facilitate electron transfer and reactant diffusion.

3. Representative MOFs • Cu-MOFs: oxidation and CO₂ fixation. • Fe-MOFs: Fenton-like catalysis and pollutant degradation. • Ni-MOFs: hydrogenation and electrocatalysis. • Zn-MOFs: photocatalysis and sensing.

4. Environmental Applications • CO₂ capture and conversion. • Degradation of organic dyes and pollutants. • Heavy metal ion adsorption. • Gas separation and purification.

5. Challenges • Limited water and thermal stability. • Difficulties in large-scale production. • Structural collapse during activation. • Metal leaching under reaction conditions.

6. Future Prospects • Development of greener synthesis methods. • Integration with other materials (MOF composites). • Enhanced recyclability and stability. • Expansion of catalytic and environmental applications.
