The novel metal-organic coordination polymers (MOCP) with the general chemical formula [Mn2L(SCN)2(OH)2]***3OH [L=1,5-bis(pyridine-4-ylmethylene) carbonohydrazide] {1} were synthesized by using two techniques, solvothermal and sonochemical ultrasonic-assisted. The effects of sonication power, reaction time, concentration of reactants, and temperature were examined on their impact on influencing the size and morphology of the *** findings have discovered that all parameters have an inverse impact on the size and morphology of 1. However, this study determined that temperature and sonication power do not control the crystals' size and morphology. SEM further analyzed the prepared microcrystals of MOCPs to examine the surface morphology and XRD, elemental evaluation composition, and FT-IR spectroscopy to clarify the functional groups of the prepared Mn-MOCPs. In the following, the calcination of 1 in the air atmosphere resulted in the production of Mn3O4 nanoparticles at 650 °C. The geometric and electronic structure of the MOCPs is evaluated in the density functional theory (DFT) framework. Molecular docking methodologies show that the best cavity of the human androgen receptor has −116.3 kJ mol−1 interaction energy involving bonding and non-bonding. © 2022, The Authors.

Routine electrolyte additives are not effective enough for uniform zinc (Zn) deposition, because they are hard to proactively guide atomic-level Zn deposition. Here, based on underpotential deposition (UPD), we propose an “escort effect” of electrolyte additives for uniform Zn deposition at the atomic level. With nickel ion (Ni 2+ ) additives, we found that metallic Ni deposits preferentially and triggers the UPD of Zn on Ni. This facilitates firm nucleation and uniform growth of Zn while suppressing side reactions. Besides, Ni dissolves back into the electrolyte after Zn stripping with no influence on interfacial charge transfer resistance. Consequently, the optimized cell operates for over 900 h at 1 mA cm −2 (more than 4 times longer than the blank one). Moreover, the universality of “escort effect” is identified by using Cr 3+ and Co 2+ additives. This work would inspire a wide range of atomic-level principles by controlling interfacial electrochemistry for various metal batteries.

A competitive complexation strategy has been developed to construct a novel electrocatalyst with Zn‐Co atomic pairs coordinated on N doped carbon support (Zn/CoN‐C). Such architecture offers enhanced binding ability of O 2 , significantly elongates the O−O length (from 1.23 Å to 1.42 Å), and thus facilitates the cleavage of O−O bond, showing a theoretical overpotential of 0.335 V during ORR process. As a result, the Zn/CoN‐C catalyst exhibits outstanding ORR performance in both alkaline and acid conditions with a half‐wave potential of 0.861 and 0.796 V respectively. The in situ XANES analysis suggests Co as the active center during the ORR. The assembled zinc–air battery with Zn/CoN‐C as cathode catalyst presents a maximum power density of 230 mW cm −2 along with excellent operation durability. The excellent catalytic activity in acid is also verified by H 2 /O 2 fuel cell tests (peak power density of 705 mW cm −2 ).

Na superionic conductor (NASICON) structured cathode materials with robust structural stability and large Na + diffusion channels have aroused great interest in sodium-ion batteries (SIBs). However, most of NASICON-type cathode materials exhibit redox reaction of no more than three electrons per formula, which strictly limits capacity and energy density. Herein, a series of NASICON-type Na 3+ x MnTi 1− x V x (PO 4 ) 3 cathode materials are designed, which demonstrate not only a multi-electron reaction but also high voltage platform. With five redox couples from V 5+/4+ (≈4.1 V), Mn 4+/3+ (≈4.0 V), Mn 3+/2+ (≈3.6 V), V 4+/3+ (≈3.4 V), and Ti 4+/3+ (≈2.1 V), the optimized material, Na 3.2 MnTi 0.8 V 0.2 (PO 4 ) 3 , realizes a reversible 3.2-electron redox reaction, enabling a high discharge capacity (172.5 mAh g −1 ) and an ultrahigh energy density (527.2 Wh kg −1 ). This work sheds light on the rational construction of NASICON-type cathode materials with multi-electron redox reaction for high-energy SIBs.

The exploitation of highly efficient carbon dioxide reduction (CO 2 RR) electrocatalyst for methane (CH 4 ) electrosynthesis has attracted great attention for the intermittent renewable electricity storage but remains challenging. Here, N-heterocyclic carbene (NHC)-ligated copper single atom site (Cu SAS) embedded in metal–organic framework is reported (2Bn-Cu@UiO-67), which can achieve an outstanding Faradaic efficiency (FE) of 81 % for the CO 2 reduction to CH 4 at −1.5 V vs. RHE with a current density of 420 mA cm −2 . The CH 4 FE of our catalyst remains above 70 % within a wide potential range and achieves an unprecedented turnover frequency (TOF) of 16.3 s −1 . The σ donation of NHC enriches the surface electron density of Cu SAS and promotes the preferential adsorption of CHO* intermediates. The porosity of the catalyst facilitates the diffusion of CO 2 to 2Bn-Cu, significantly increasing the availab.lity of each catalytic center.
