Hierarchical Porous Integrated Co1−xS/CoFe2O4@rGO Nanoflowers Fabricated via Temperature‐Controlled In Situ Calcining Sulfurization of Multivariate CoFe‐MOF‐74@rGO for High‐Performance Supercapacitor

“…[ 7 ] On the one hand, the variable metal nodes and special periodic arrangement not only open up possibility for the introduction of bimetals but also regulate their ratio. [ 8 ] On the other hand, the hierarchical metal@C structure could be readily evolved from the porous framework via simple calcination, which can offer favorable environment for electron transmission and effectively reduce the agglomeration of active nanoparticles (NPs) due to the periodic barrier of linkers. [ 9 ] Apparently, an in situ calcination of bimetallic MOF and sulfur provides a convenient way for the preparation of integrative BMO/MS hybrid materials.…”

Phosphorous-doped bimetallic sulfides embedded in heteroatom-doped carbon nanoarrays for flexible all-solid-state supercapacitors

“…At the same time, the surfaces of the nanosheets became rough with many nanometer-sized spherical particles. This surface evolution was mainly caused by the etching of S 2− ions [35], and the metal groups aggregated into nanoparticles during the thermal process, a phenomenon that has also appeared in previous studies [36][37][38][39]. The exact composition of the ZCS/HC was measured by energy-dispersive X-ray spectroscopy (EDS) tests, as shown in Fig.…”

A High‐Capacity Negative Electrode for Asymmetric Supercapacitors Based on a PMo12 Coordination Polymer with Novel Water‐Assisted Proton Channels

“…[4] The two main types of supercapacitors include: [5] (i) electrochemical double layer capacitors (EDLCs) that store charge through charge polarization at the electric double layer and (ii) pseudocapacitors that store the charge derived from certain redox processes. [6,7] Therefore, a feasible method to boost the specific capacitance is to choose pseudocapacitance materials to replace the EDLCs materials since pseudocapacitance capacitors can reach 10-100 times the specific capacitance of EDLCs under the same electrode area conditions.
