Supercapacitive amino-functionalized cobalt and copper metal-organic frameworks with varying surface morphologies for energy storage

Structural Engineering of Co‐Metal–Organic Frameworks via Ce Incorporation for Improved Oxygen Evolution

“…[ 29 ] The peaks at 1589 cm −1 were attributed to the coordinated carboxylate group, [ 30 ] and the peak that appeared at 1309 cm −1 was related to the stretching vibration of C─N. [ 31 ] For the as‐prepared MOFs, one can also see that the NH 2 ‐H 2 BDC linker after binding with Co‐salt, the double sharp peaks of a typical symmetric and asymmetric NH 2 stretching vibrations (3508 and 3389 cm −1 ) became weak and shifted to lower stretching frequencies at 3487 and 3311 cm −1 , respectively. This could be due to Co coordination with electron‐donating oxygen atoms from the carboxylic group.…”

“…This could be due to Co coordination with electron‐donating oxygen atoms from the carboxylic group. [ 31 ] Simultaneously, the peak of a typical coordinated carboxylate group stretching vibrations shifted to lower stretching frequencies. Furthermore, the new peak range of 738–611 cm −1 representing the Co─O bond [ 32 ] stretch vibration can be found in the spectra of the as‐prepared MOFs.…”

Nanoproteases: Alternatives to Natural Protease for Biotechnological Applications

“…MOFs have a highly porous crystal structure formed from metaloxygen clusters (or metal ions) and organic linkers. [64] These hybrid inorganic-organic materials have infinite 3D structures and large accessible surface areas with huge potentials as sensors, [65] energy storage materials, [66] filters, [67] absorbents [68] and catalysts. [69] In 2014, Li et al [70] reported that a metal organic frameworks (Cu-MOF, Cu 2 (C 9 H 3 O 6 ) 4/3 ) has a trypsin-like activity and can hydrolyze bovine serum albumin (BSA).…”

Snowflake-like Cu-BDC-NH2/Cu58S32 Binary Nanohybrid for H2 Evolution and O2 Reduction

“…in the organic linkers could show a bathochromic shift along with modification of the HOMO energy level . In terms of photocatalytic activation of atmospheric molecules, MOFs like UiO-66 (Zr), Ni-MOF, MIL-125 (Ti), MIL-53 (Al, Cr, Fe), MIL-88B (Fe) and ZIF have been explored intensively. ,, However, copper coordinated amino-functionalized benzenedicarboxylate MOF (Cu-BDC-NH 2 ) with paddle-wheel-like architecture containing solvent-exchangeable open metal sites is rarely explored for activation of atmospheric molecules. , Recently, Cu-BDC-NH 2‑ based heterostructure materials have been utilized for various applications like peroxidase mimicking activities, fluorescent sensing, adsorbent, supercapacitor application, CO 2 reduction, dye degradation, and overall water splitting. − In addition, the synthesis and photocatalytic application of metal sulfide-based heterojunctions containing Cu-BDC-NH 2 as a photoactive component is yet to be studied. To construct high-efficacy heterostructure materials, various nonconventional strategies like core–shell configuration, template-assisted synthesis, and hierarchical and epitaxial growth have been employed recently. , Among all of these, the template-assisted self-assembled growth of heterostructure materials displays an oriented and controlled topology that provides high interfacial contact for synergistic charge channelization.…”
