A hybrid of MIL-53(Fe) and conductive sulfide as a synergistic electrocatalyst for the oxygen evolution reaction

Abstract

<p>The development of effective electrocatalysts for sustainable energy conversion and storage is highly desired, but still a considerable challenge due to the sluggish oxygen evolution reaction (OER). Herein, we report...</p>

Coordination Polymer-Derived Fe3N Nanoparticles for Efficient Electrocatalytic Oxygen Evolution

“…R s is the solution resistance or the uncompensated series resistance, whose value is the intercept at the horizontal axis. CPE ( Q ) and R ct correspond to the constant phase element and the charge-transfer resistance, respectively . The values of the parameters are shown in Table S2.…”

Accurately Regulating the Electronic Structure of NixSey@NC Core–Shell Nanohybrids through Controllable Selenization of a Ni‐MOF for pH‐Universal Hydrogen Evolution Reaction

“…In recent years, metal–organic frameworks (MOFs), as a new class of organic–inorganic hybrids comprising metal ions or clusters connected by organic ligands, have been widely used as precursors to fabricate carbon‐ and transition metal‐based electrocatalysts. [ 15–17 ] Taking advantage of the tunability of MOFs, TMSs@HCM core–shell nanohybrids with desired electronic structure and chemical compositions can be easily constructed via the facilely in situ selenization process without the introduction of external carbon and heteroatom sources. [ 18–20 ] Meanwhile, utilizing MOFs as templates or precursors, the active catalysts could not only well inherit intrinsic structure advantages of MOFs, but also protect them from aggregation with the homogeneously dispersed transition metal ions in the MOFs’ precursors.…”

In‐situ Electrochemical Activation Enhances the OER Catalytic Performance of Ag NWs@ZIF‐67 in Alkaline Simulated Seawater

“…[15,16] Since heat treatment will destroy the original structure of MOFs, [17] combining some conductive materials (such as metals and carbon materials) with MOFs has become the main direction of current research. [18][19][20] In-situ electrochemical activation provides a new idea for directly modifying MOFs in the catalytic field without destroying the framework structure. [21] Taking the above factors into consideration, the conductive properties of MOFs were improved by directly anchoring 2D-ZIF 67 nanosheets on silver nanowires through a bottom-up concentration-controlled approach.…”

“…According to most previous reports, MOFs materials used for catalysis generally appear as precursors, and a series of nanocomposites with excellent catalytic activity were obtained through heat treatment [15,16] . Since heat treatment will destroy the original structure of MOFs, [17] combining some conductive materials (such as metals and carbon materials) with MOFs has become the main direction of current research [18–20] . In‐situ electrochemical activation provides a new idea for directly modifying MOFs in the catalytic field without destroying the framework structure [21]…”
