“…In particular, graphene-based materials have been studied to enhance their electrochemical capacitive properties. To achieve this, several research groups have attempted to create N-doped graphene (N-G)-type materials from MOFs, specifically ZIF-8, or integrate the structural advantages of ZIF-8 with graphene [57][58][59][60][61][62][63]. In this section, as series of such research initiatives are reviewed, focusing on the ideas, synthesis processes, material structures, and reported capacitive performances.…”

In recent years, graphene-type materials originating from metal–organic frameworks (MOFs) or integrated with MOFs have exhibited notable performances across various applications. However, a comprehensive understanding of these complex materials and their functionalities remains obscure. While some studies have reviewed graphene/MOF composites from different perspectives, due to their structural–functional intricacies, it is crucial to conduct more in-depth reviews focusing on specific sets of graphene/MOF composites designed for particular applications. In this review, we thoroughly investigate the syntheses, characteristics, and performances of N-G/MOF(ZIF-8)-based/derived materials employed in electrochemical energy conversion and storage systems. Special attention is given to realizing their fundamental functionalities. The discussions are divided into three segments based on the application of N-G/ZIF-8-based/derived materials as electrode materials for batteries, electrodes for electrochemical capacitors, and electrocatalysts. As electrodes for batteries, N-G/MOF(ZIF-8) materials can mitigate issues like an electrode volume expansion for Li-ion batteries and the ‘shuttle effect’ for Li-S batteries. As electrodes for electrochemical capacitors, these materials can considerably improve the ion transfer rate and electronic conductivity, thereby enhancing the specific capacitance while maintaining the structural stability. Also, it was observed that these materials could occasionally outperform standard platinum-based catalysts for the electrochemical oxygen reduction reaction (ORR). The reported electrochemical performances and structural parameters of these materials were carefully tabulated in uniform units and scales. Through a critical analysis of the present synthesis trends, characteristics, and functionalities of these materials, specific aspects were identified that required further exploration to fully utilize their inherent capabilities.

“…[16][17][18][19][20][21] The exceptional conductivity of ZIF-67 holds promise to compensate for the insu cient electrical conductivity of WO3, thereby enhancing electron conduction and improving the charge-discharge e ciency of batteries. [22] The introduction of ZIF-67 into the composite material effectively alleviates the volume expansion issue of WO3, enhancing the structural stability of the electrode and improving the cyclic performance and capacity retention of the battery. [23][24][25] ZIF-67 in the composite material may exhibit favorable lithium-ion intercalation capabilities, increasing energy storage capacity and enhancing the energy density of the battery.…”

In this work, the high porosity of ZIF-67 frame was used to increase the infiltration degree of electrolyte, improve the diffusion rate of ions and inhibit the volume expansion of WO3/CoWO4 during the cycling process. The high conductivity of rGO was used to make up for the lack of conductivity of composite materials. At the current density of 100 mA g− 1, 507.8 mAh g− 1 specific capacity was retained after 100 cycles and 248.3 mAh g− 1 specific capacity was retained after 300 cycles at the current density of 800 mA g− 1.
