“…[22,23] Thus,w es peculated that salen-containing frameworks and polymers may display good electrocatalytic OER performance, because salen-CMPs combine the rigid conjugated porous structure of CMPs and the intrinsic electrocatalytic activity of the salen moiety. [24][25][26][27][28][29][30] In this work we have demonstrated the ability of salen-containingp olymers to act as electrocatalysts for the first time. The electrochemical test results showed that the catalyst salen-CMP-Fe-3 showed the highest OER activity.W hen loaded onto glass carbon electrodes, the prepared salen-CMP-Fe-3 electrodes demonstratedas mall Tafel slope of 63 mV dec À1 and an overpotentialo f2 38 mV at 10 mA cm À2 in 0.1 m KOH.…”

Exploring high‐performance electrocatalysts, especially non‐noble metal electrocatalysts, for the oxygen evolution reaction (OER) is critical to energy storage and conversion. Herein, we report for the first time that conjugated microporous polymers (CMPs) incorporating salen can be used as OER electrocatalysts with outstanding performances. The best OER electrocatalyst (salen‐CMP‐Fe‐3) exhibits a low Tafel slope of 63 mV dec−1 and an overpotential of 238 mV at 10 mA cm−2. DFT and Grand Canonical Monte Carlo calculations confirmed that the significantly improved electrocatalytic properties can be attributed to the intrinsic catalytic activity of the salen moiety and the enrichment effect of the pore structures. This work demonstrates that salen‐based conjugated polymers are a type of metal‐coordinated porous polymer that show excellent catalyst performance.

“…In recent years, there has been a rapid growth in the development of novel supported compounds such as supported catalysts, reagents, sensors and adsorbents. [1][2][3][4][5][6][7] Therefore, nanoparticles have been widely used as solid supports for the immobilization of homogeneous catalysts. [8][9][10] For example, silica materials, [11] polymers, [12] graphene oxide, [13][14][15][16] carbon nanotubes, [17] iron oxide, [18] ionic liquids, [19,20] boehmite nanoparticles, [21,22] biochar, [23] magnetic nanoparticles, [24][25][26] etc.…”

In this work, a green approach is reported for efficient synthesis of biologically active tetrazole and pyranopyrazole derivatives in the presence of Cu-Cytosine@MCM-41 and Ni-Cytosine@MCM-41 (copper (II) and nickel (II) catalyst on the modified MCM-41 using cytosine). The synthesis of tetrazoles and pyranopyrazoles in the presence of these catalysts was performed in green solvents such as water or poly (ethylene glycol) (PEG). All products were obtained in high TOF (turnover frequency) numbers in the presence of these catalysts, which indicate the high efficiency of these catalysts in the synthesis of tetrazole and pyranopyrazole derivatives. The prepared catalysts were characterized by various techniques such as BET, TGA, XRD, FT-IR, SEM, EDS, WDX, TEM, and AAS. Mesoporous structure of these catalysts was confirmed by nitrogen adsorptiondesorption isotherms. These catalysts can be recovered and reused for several runs without significant change in their catalytic activity or metal capacity. The recovered catalysts have been characterized by XRD, SEM, EDS, WDX, FT-IR and AAS techniques, by which their heterogeneous nature has been confirmed.
