“…In general, the lower electronegativity of P than O in their respective compounds is conductive to electron transport and redox reactions, resulting in the ideal electrical conductivity and high theoretical capacitance of the transition metal phosphide. ZIF‐67, a typical template and precursor, has been chosen for the preparation of Zn 0.33 Co 0.67 P/NF, [ 126 ] CoP N‐doped carbon polyhedrons/rGO, [26a] and Ni‐doped CoP@C/CNT, [26b] delivering specific capacitances of 2115.5 1 , 466.6, and 708.1 F g −1 at 1 A g −1 , respectively.

Metal-organic frameworks (MOFs) are deemed an attractive type of active material during electrochemical reaction processes because of their unique compositional and structural superiority, as well as the dual role as both templates and precursors to derive a large variety of functional materials for energy conversation and storage. Herein, reviewing the recent advances of MOFs and their derived functional materials as electrode materials in supercapacitors, which are classified into pristine MOFs, MOF composites, and MOF-derived functional materials, is focused on. Their synthetic routes and modification strategies are summarized and the relationship between the diversity of the architectures and compositions of MOF-based materials and their electrochemical performance is discussed. In addition, the challenges and opportunities on future research and extensive applications of MOFs and their derived functional materials are offered.

“…According to electronic properties calculations, Ni-doping yields an increased ratio of free electrons in Ni-CoP, resulting in better charge transmission behavior during electrochemical reactions. Consequently, the Ni-CoP@C@CNT electrode delivered a higher specific capacitance of 708.1 F g −1 than CoP@C of 349.2 F g −1 [ 112 ] but lower than the ZIF-67-derived sulfide Co 3 S 4 of 1416 F g −1 at 1 A g −1 [ 110 ]. The Ni-CoP@C@CNT//graphene ASC advice presents an eminent electrochemical cycling stability, with a capacitance retention as high as 117% [ 112 ].…”

View full text Add to dashboard Cite

Supercapacitors (SCs), one of the most popular types of energy-storage devices, present lots of advantages, such as large power density and fast charge/discharge capability. Being the promising SCs electrode materials, metal–organic frameworks (MOFs) and their derivatives have gained ever-increasing attention due to their large specific surface area, controllable porous structure and rich diversity. Herein, the recent development of MOFs-based materials and their application in SCs as the electrode are reviewed and summarized. The preparation method, the morphology of the materials and the electrical performance of various MOFs and their derivatives (such as carbon, metal oxide/hydroxide and metal sulfide) are briefly discussed. Most of recent works concentrate on Ni-, Co- and Mn-MOFs and their composites/derivatives. Conclusions and our outlook for the researches are also given, which would be a valuable guideline for the rational design of MOFs materials for SCs in the near future.

“…[11] Based on the density functional theory (DFT), Sun et al studied the influence of Ni doping on the properties of CoP electrons, and the results indicate that the Co electron state around the Fermi level is changed by the Ni outermost orbit and thus there is a synergetic effect between Ni and Co, which effectively promotes redox kinetics. [12] As a result, bimetallic phosphides with appropriate adsorption and catalytic abilities are a promising option for solving the above problems. However, designing the structure of bimetallic NiÀ Co phosphides to expose more active sites is the key to further improve the electrochemical performance.…”

Expedited conversion by using a catalyst has emerged as one of the most effective methods to suppress the shuttle effects in LiÀ S batteries. The application of accelerating conversion through bidirectional catalysts to address the adverse effects of the shuttle effect on batteries has caused extensive concern. Here, bimetallic nickel-cobalt phosphide-based yolk-shell spheres loaded on reduced graphene oxide (NiCo 2 P X /rGO) are designed as bidirectional catalysts, which integrates the merits of NiCo 2 P X and rGO to facilitate the redox reaction kinetics, resulting in rapid deposition during discharging and fast decomposition during charging of the end products (Li 2 S). The porous yolk-shell structure synthesized by the anion exchange method exposes more catalytic sites for massive host-guest interaction. Based on its unique function and structure, the sulfur cathode with NiCo 2 P X /rGO delivers a high capacity of 1238.7 mAh g À 1 at 0.1 C and maintains a stable discharge capacity of 561.1 mAh g À 1 after 400 cycles at 1 C. This study explores the bidirectional catalysis of polysulfides with bimetallic phosphide materials, which provides a new choice for nextgeneration lithium-sulfur batteries.
