A two-component nanocomposite of copper hexacyanoferrate/reduced graphene oxide (CuHCF/rGO) was successfully synthesized using a solutionbased co-precipitation process in the presence of graphene oxide solution. Electrochemical measurements indicated a specific capacitance of 548 F g −1 at a current density of 0.5 A g −1 in the potential range of −0.2 to 1 V, versus Ag/ AgCl standard electrode, obtained in an electrolyte of 0.5 M K 2 SO 4 (as a neutral electrolyte) during galvanostatic charge/discharge cycles. This value is higher than the specific capacitance of the raw materials rGO (174 F g −1 at a current density of 0.5 A g −1 ) and CuHCF (236 F g −1 at a current density of 0.5 A g −1 ), which is rooted in the activation of copper ions in the electrochemical reaction and some synergistic effects (observed between rGO and CuHCF). The rGO/ CuHCF nanocomposite electrode was able to retain 83% of its initial capacitance after 1000 cycles at a current density of 3 A g −1 .

“…The designed device can deliver an energy density of 45.0 Wh kg −1 at the power density of 857.7 W kg −1 . Even after the power density increased to 13.6 KW kg −1 , the device still demonstrates an energy density of 36.8 Wh kg −1 , outperforming most of the excellent energy storage devices (Figure e), such as nickel‐cobalt phosphate//AC, NiNTAS@Fe 2 O 3 //NiNTAS@MnO 2 , Ni 0.55 Co 0.45 C 2 O 4 //AC, Ni‐Co LDH@NF//NiCoO 2 @NF, CoNi‐MOF//AC, and CC@NiCo 2 Al‐LDH//CC@ZPC . Moreover, the asymmetric device shows excellent cycling stability with retention of 87.7% at a current density of 12 A g −1 after 5000 cycles (Figure f), suggesting the robust interconnected networks and reasonable strain accommodation of the hybrid electrode.…”

Redox Tuning in Crystalline and Electronic Structure of Bimetal–Organic Frameworks Derived Cobalt/Nickel Boride/Sulfide for Boosted Faradaic Capacitance

The development of efficient electrode materials is a cutting‐edge approach for high‐performance energy storage devices. Herein, an effective chemical redox approach is reported for tuning the crystalline and electronic structures of bimetallic cobalt/nickel–organic frameworks (Co‐Ni MOFs) to boost faradaic redox reaction for high energy density. The as‐obtained cobalt/nickel boride/sulfide exhibits a high specific capacitance (1281 F g−1 at 1 A g−1), remarkable rate performance (802.9 F g−1 at 20 A g−1), and outstanding cycling stability (92.1% retention after 10 000 cycles). An energy storage device fabricated with a cobalt/nickel boride/sulfide electrode exhibits a high energy density of 50.0 Wh kg−1 at a power density of 857.7 W kg−1, and capacity retention of 87.7% (up to 5000 cycles at 12 A g−1). Such an effective redox approach realizes the systematic electronic tuning that activates the fast faradaic reactions of the metal species in cobalt/nickel boride/sulfide which may shed substantial light on inspiring MOFs and their derivatives for energy storage devices.

In recent years, research efforts have been focused on the design and fabrication of highly efficient catalysts for liquid fuel cells, because the use of these cells is an important approach for alleviating environmental pollution and energy crises. However, the limitations of the catalytic performance of industrial Pt/C have strongly hindered the development of these fuel cells. The catalyst morphology has a strong impact on its performance; nanostructured catalysts are preferred as they offer large specific surface area and more exposed active centers. In view of this, many catalysts with unique structures have been synthesized in recent years, all of which show excellent catalytic performance characteristics. Despite these achievements, few efforts have been made to survey this field comprehensively. Herein, the recent advances in catalysts for liquid fuel cells are summarized, with a focus on noble metal catalysts with unique morphologies such as nanowires, nanosheets, and assembly structures. Their formation mechanisms are discussed critically. The relationship between the unique morphologies and excellent performance of these catalysts is also explored. This work may provide guidelines for the further development of liquid fuel cells.
