Abstract As inspired by the Mn 4 CaO 5 oxygen evolution center in nature, Mn-based electrocatalysts have received overwhelming attention for water oxidation. However, understanding of detailed reaction mechanism has been a long-standing problem. Herein, homologous KMnPO and •H 2 O with 4-coordinated 6-coordinated centers, respectively, are prepared. The two catalysts constitute an ideal platform to study structure-performance correlation. presence Mn(III), Mn(IV), Mn(V) intermediate species...
Abstract Metal oxides with spinel structure have garnered increasing attention as promising alternatives to noble metal‐based electrocatalysts. However, these electrocatalysts often fail simultaneously exhibit high activity and stability for both hydrogen evolution reaction (HER) oxygen (OER), limiting their applications in electrocatalytic water splitting. Herein, crystalline/amorphous heterogeneous interfaces are successfully introduced into NiCo 2 O 4 nanosheets, which grown situ on...
Abstract Multinuclear metal clusters are ideal candidates to catalyze small molecule activation reactions involving the transfer of multiple electrons. However, synthesizing active is a big challenge. Herein, on constructing an unparalleled Co 4 (SO ) cluster within porphyrin‐based metal–organic frameworks (MOFs) and electrocatalytic features such for oxygen evolution reaction (OER) reduction (ORR) reported. The II sulfate complexes tetrakis(4‐pyridyl)porphyrin under solvothermal conditions...
The effect of proton transfer on water oxidation has hardly been measurably established in heterogeneous electrocatalysts. Herein, two isomorphous manganese phosphates (NH4 MnPO4 ⋅ H2 O and KMnPO4 O) were designed to form an ideal platform study the oxidation. hydrogen-bonding network NH4 proven be solely responsible for its better activity. differences kinetics materials indicate a fast hopping process with low activation energy O. In addition, can effectively promote between adjacent Mn...
Abstract Metal‐coordinated N‐doped carbon (M‐N‐C) materials with highly curved structures have become a promising class of electrocatalysts for the oxygen reduction reaction (ORR). However, stability these remains problem due to traditional post‐metal loading strategy. Herein, single‐atomic Co‐N‐C active sites anchored on helical carbonaceous nanotubes (HCNTs) are prepared (Co‐N‐C@HCNT) by pyrolyzing Co porphyrins and polypyrroles (PPys) mixtures at high‐temperature one‐step method....
Abstract Molecular electrocatalysis requires the immobilization of molecular catalysts on electrode materials for practical uses. Direct adsorption catalyst molecules is simple, but grafting through chemical bonds can significantly improve electrocatalytic efficiency and durability. However, designing synthesizing to simultaneously catalytic activities realize easy electrodes challenging. The study herein reports a one‐pot strategy graft Co corroles pyridine‐modified carbon nanotubes (CNTs)...
The practical application of lithium–oxygen (Li–O2) batteries is limited by the formation lithium dendrites and use flammable unstable organic liquid electrolytes, which would cause safety issues poor cycling stability. Herein, we present a bilayer organic/inorganic hybrid solid-state electrolyte to improve enhance electrochemical performance Li–O2 batteries. Si-doped NASICON-type Li1.511Al0.5Ge1.5Si0.01P2.99O12 (LAGP-Si) serves as an inorganic rigid backbone guarantee high ionic...

Negligible amounts iron solubilized under similar conditions. Bacillus GJ 33 significantly accelerated reduction solubilization chemical means thereby also nickel cobalt, and, advanced stages, copper. Nickel directly dependent on copper only partly it. Some nodule substance as a...

Herein, two manganese phosphates with identical bulk structures but different properties are designed to form an appealing platform investigate oxidation. The uniform MnO6 site and similar physical avoid unfair comparisons performance. situ Raman X-ray absorption spectral results demonstrate that flexibility catalyst proton-accepting sites favorable from spectroscopic studies...

Autologous Co 3 (PO 4 ) 2 showed higher OER activity than that of (OH) (HPO . This was because the four-coordination II possessed a high turnover frequency and easily transformed into high-valent active cobalt(hydr)oxide species.
