Unlocking catalytic potential: a rhodium(II)-based coordination polymer for efficient carbene transfer reactions with donor/acceptor diazoalkanes.

Herein, we report the use of a molecular-defined rhodium(II) coordination polymer (Rh-CP) as a heterogeneous, recyclable catalyst in carbene transfer reactions. We showcase the application of this heterogeneous catalyst in a range of carbene transfer reactions and conclude with the functionalization of natural products and drug molecules.

Bimetallic CPM-37(Ni,Fe) metal-organic framework: enhanced porosity, stability and tunable composition.

A newly synthesized series of bimetallic CPM-37(Ni,Fe) metal-organic frameworks with different iron content (Ni/Fe ≈ 2, 1, 0.5, named CPM-37(NiFe), CPM-37(NiFe) and CPM-37(NiFe)) demonstrated high N-based specific surface areas of 2039, 1955, and 2378 m g for CPM-37(NiFe), CPM-37(NiFe), and CPM-37(NiFe), having much higher values compared to the monometallic CPM-37(Ni) and CPM-37(Fe) with 87 and 368 m g only. It is rationalized that the mixed-metal nature of the materials increases the structural robustness due to the better charge balance at the coordination bonded cluster, which opens interesting application-oriented possibilities for mixed-metal CPM-37 and other less-stable MOFs.

Efficient Electrochemical Lead Detection by a Histidine-Grafted Metal-Organic Framework MOF-808 Electrode Material.

As the excessive presence of heavy metals in the environment significantly affects human health, it becomes necessary to develop efficient, selective, and sensitive methods for their detection. In this study, a novel electrochemical sensor for the detection of Pb ions is described. The proposed sensor is based on a glassy carbon electrode (GCE) modified by a thin film of histidine-grafted metal-organic framework (MOF-808-His).

Exceptionally Stable And Super-Efficient Electrocatalysts Derived From Semiconducting Metal Phosphonate Frameworks.

Two new isostructural semiconducting metal-phosphonate frameworks are reported. Co [1,4-NDPA] and Zn [1,4-NDPA] (1,4-NDPA is 1,4-naphthalenediphosphonate) have optical bandgaps of 1.7 eV and 2.

The efficient removal of ibuprofen, caffeine, and bisphenol A using engineered egusi seed shells biochar: adsorption kinetics, equilibrium, thermodynamics, and mechanism.

Contaminants of emerging concern (CECs), also known as micropollutants, have been recognized in recent years as substantial water pollutants because of the potential threats they pose to the environment and human health. This study was aimed at preparing biochar (BC) based on egusi seed shells (ESS) with well-developed porosity and excellent adsorption capacity towards CECs including ibuprofen (IBP), caffeine (CAF), and bisphenol A (BPA). BC samples were prepared by pyrolysis at different temperatures (400 to 800 °C) and were characterized using nitrogen sorption, FTIR, powder X-ray diffraction (PXRD), SEM/EDS, elemental analysis, and thermal analysis.
