Porphyrinic metal–organic frameworks as molybdenum adsorbents for the ⁹⁹Mo/^99mTc generator

Abstract

Two porphyrinic metal–organic frameworks (PCN-222 and PCN-224) were prepared and their potential as molybdenum adsorbents for the 99Mo/99mTc generator was explored.

Enhanced photoreduction efficiency of Cr(vi) driven by visible light in a new Zr-based metal–organic framework modified by hydroxyl groups

“…In particular, the Zr spectrum could be deconvoluted into two characteristic peaks of Zr 3d 5/2 at 182.2 eV and Zr 3d 3/2 at 184.6 eV. 66 Finally, the N 2 isotherm measurements revealed that the N 2 sorption capacity of the activated HCMUE-1 at P / P o = 0.95 was lower than the theoretically predicted data (Fig. S5†).…”

Cu-Metalated Porphyrin-Based MOFs Coupled with Anatase as Photocatalysts for CO2 Reduction: The Effect of Metalation Proportion

“…This was accompanied by the disappearance of the peak assigned to the N-H in-plane bending vibration of pyrrolic nitrogen (centered at ca. 963 cm −1 ) [34][35][36] that was only observed in the MOF-a material developed using the free-base H2TCPP. These data suggest that Cu 2+ remained in the porphyrin core even after the development of the MOF structure.…”

“…To further evidence the TCPP metalation, infrared spectra were also recorded (Figure S2b). The peak centered at 966 cm −1 assigned to the N-H in-plane bending vibration of pyrrolic nitrogen became undetectable after the treatment with Cu 2+ , suggesting an interaction between the -NH groups inside the porphyrin ring and copper ions [34][35][36]. In addition, a peak at ca.…”

Chestnut-like Molybdenum-Doped Nickel Cobaltite Spinel Oxide Nanoparticles Grown on Ni Foam as the Electrocatalyst for the Hydrogen Evolution Reaction

“…The Mo 3d spectra was detected with well-defined splitting of 3d 5/2 and 3d 3/2 components having Δ BE = 3.1 eV, as shown in Figure e. The core level peaks observed at 231.8 and 234.9 eV are attributed to the Mo 3d 5/2 and Mo 3d 3/2 spin–orbit doublet states indicated to Mo 6+ , which proved that Mo-substituted the NiCo 2 O 4 successfully …”
