“…The resulting material showed enhanced surface area, higher content of N‐dopants and therefore higher ORR catalytic activity compared to the counterpart derived from BTC‐added chitosan–Fe complex. Hareesh and co‐workers [ 205 ] mixed Fe–BTC MOG with melamine formaldehyde polymer, which were allowed to propagate simultaneously to form interpenetrating polymer networks. The networks after pyrolysis led to a high degree of surface area and good distribution of graphitic N; both were responsible for efficient alkaline ORR electrocatalysis.…”

Synthesis and Performance of MOF-Based Non-Noble Metal Catalysts for the Oxygen Reduction Reaction in Proton-Exchange Membrane Fuel Cells: A Review

“…An Fe/N-doped porous graphitic carbon (Fe-MOG-MFN-C) was synthesized by pyrolyzing (in N 2 ) an interpenetrating polymer network (IPN) comprising melamine formaldehyde (hard segment) and a metal–organic gel (MOG, soft segment) in the presence of naphthalene ( Figure 16 ) [ 125 ]. SEM imaging showed a sheet-like graphitized carbon structure with abundant macropores, while elemental mapping confirmed the homogeneous distribution of N and Fe in the carbon matrix.…”

Zirconium-based metal–organic framework gels for selective luminescence sensing

“…Metal-organic gels combine the advantages of stimuli-response of physical gels (weak non-covalent interactions) and stability of chemical gels (strong chemical bonds). [1][2][3][4] Metal-organic gels have found applications in various elds such as sensing, [5][6][7][8][9][10] catalysis, [11][12][13][14] environmental remediation, 15,16 renewable energy conversion, [17][18][19] and templates for nanomaterials. 20 Metalorganic framework (MOF)-based gels are particularly interesting because they incorporate MOF nanoparticles with well-dened microporosity in their gel matrix.…”
