“…It is specifically associated with Ag(I) ion coordinated to a carboxylic group, such as the BTC, as opposed to the more common forms of silver such as oxide, salt, or metallic silver . From previous studies, it is known that the Ag(I) interactions in the AgBTC contain Ag−O coordination bond as expected, in addition to metallic Ag(I)‐Ag(I) bond of every two adjacent silver ions.…”

“…(CCDC 631984), with orthorhombic structure (space group: F d d d (70)), which was synthesized using a similar procedure. By comparison to the literature the main peaks of the AgBTC were identified . The powder XRD of the AgBTC@AC gives only the diffraction of the carbon, probably due to the low content of the complex in the carbonaceous support, which seems to hinder the MOF signal, and due to the expected peaks broadening of the AgBTC nanoparticles, according to Scherrer equation …”

Silver is known as a viable alternative for platinum group metals for the catalysis of the oxygen reduction reaction in alkaline electrolyte. Unlike most other platinum-group metal-free catalysts, usually organo-metallic complexes, silver is commonly used in its metallic form (Ag(0)). Herein, we describe the preparation, characterization, and electrochemical activity of a unique silver-based catalyst, based on Ag(I) ions coordinated to oxygen groups in an organic ligand (benzene tricarboxylic acid -BTC) which forms a metal organic framework, similar to first-row transition metal-based catalysts in metal organic frameworks. When the silver-based catalyst is incorporated in a porous carbon support, it exhibits high electrocatalytic activity for the oxygen reduction reaction, with a distinct electrochemical behavior, different than metallic silver. In addition, the use of the ionic form of the silver, which is atomically dispersed, allows to lower its loading of the metal by at least one order of magnitude when compared to other reported silver-based oxygen reduction reaction catalysts. Results and DiscussionAg-BTC and Ag-BTC@AC were synthesized according to the procedure described in the experimental section. Two-probes bulk conductivity measurements showed that the AgBTC is practically an insulator, as many other metal-BTC, [5,8] unlike the high electronic conductivity of metallic silver. Therefore, AgBTC cannot be utilized as a stand-alone electrocatalyst/electrode in [a] S.

A new copper (II) coordination complex formulated as [Cu (dipic)(phen)(2‐MePy)]. 2H2O (1) where phen = 1, 10‐phenanthroline, dipic2− = pyridine‐2,6‐dicarboxylato and 2‐MePy = 2‐methyl pyrrole was synthesized through a simple and environment‐friendly reaction under ultrasound irradiation. Also, complex 1 was synthesized by hydrothermal process at 120 °C for 3 days. The corresponding structure of complex 1 was characterized by elemental analysis, atomic absorption spectroscopy (AAS), inductively coupled plasma (ICP), conductivity measurement, Fourier‐transform infrared spectroscopy (FT‐IR), Raman spectroscopy, ultraviolet–visible spectroscopy (UV–Vis), thermal gravimetric analysis (TGA), differential thermal analysis (DTA), scanning electron microscopy (SEM), vibrating sample magnetometer (VSM) and fluorescence. The crystal structure of the hydrothermally synthesized complex was characterized by single crystal X‐ray diffraction (SC‐XRD(, which revealed a triclinic structure. In the remainder of this study, the Cu2O nanoparticles have been prepared via thermal decomposition of hydrothermal and ultrasound complexes and characterized by ICP, FT‐IR, powder X‐ray diffraction (XRD), SEM and N2 adsorption/desorption. Adsorption and visible‐light‐driven photocatalytic capabilities of two synthetic Cu2O were investigated in the removal of MB from water. The result showed that the synthesized catalysts have good catalytic activity and the photocatalytic degradation is more effective in dye removal of MB compared with the adsorption.
