“…The absence of Ni diffraction peaks indicates that its ions replace the Co ions by being integrated in the matrix of the ZIF-67 crystal. Figure 2c con rms that the composite was well prepared, hence the peaks of Z67.Ni and MS were observable however, some peaks of 1T-MS are not appear in Z67.Ni/MS may be related to the high crystallinity of ZIF-67 crystals in comparison to MS [31].…”

“…Additionally, the specific crystal structure is revealed by X‐ray diffraction (XRD) patterns (Figure S22, Supporting Information). Obviously, in addition to characteristic peak of GS and VAGS at around 26° ((001) plane of graphite), the VAGS/ZIF‐67 shows some new characteristic peaks belonging to ZIF‐67 without any impurity, [ 28 ] confirming the high crystallinity of VAGS/ZIF‐67. Similarly, compared with GS and VAGS, the Raman spectra of VAGS/ZIF‐67 delivers a new characteristic peak [ 29 ] at around 700 cm −1 , also elucidating the presence of ZIF‐67 (Figure S23, Supporting Information).…”

Efficient manufacture of electroactive vertically‐oriented nanosheets with enhanced electrolyte mass diffusion and strong interfacial redox dynamics is critical for realizing high energy density of miniature supercapacitor (SC), but still challenging. Herein, microfluidic droplet printing is developed to controllably construct vertically‐oriented graphene/ZIF‐67 hetero‐microsphere (VAGS/ZIF‐67), where the ZIF‐67 is coordinately grown on vertically‐oriented graphene framework via Co─O─C bonds. The VAGS/ZIF‐67 shows ordered porous channel, high electroactivity and strong interfacial interaction, providing rapid electrolyte diffusion dynamics and high faradaic capacitance in KOH solution (1674 F g−1, 1004 C g−1), which are verified by computational fluid dynamics (CFD) and density functional theory (DFT). Moreover, the VAGS/ZIF‐67 based SC exhibits large energy density (100 Wh kg−1), excellent durability (10 000 cycles and high/low temperature), and robust power‐supply applications in portable electronics.

Graphene research continues to advance into many territories, and in this study, an exhaustive analysis of the fabrication and performance of zeolite/graphene composites is attempted for the first time. Apart from zeolite/graphene applications, the potential of graphene composites with other materials has been presented. Future perspectives and challenges have been presented extensively to enable researchers to explore the synergy of graphene composites for various unexplored applications. Carbon atoms are arranged in a two-dimensional plate-like pattern to produce the hexagonal network-shaped material known as graphene, which has a material thickness of one atom. Zeolites are frequently employed widely as heterogeneous catalysts in a variety of chemical industries due to their enormous surface area and constant pore size. Recently, scientists have worked to better understand how graphene and zeolite work together as a composite catalyst. The removal of dyes, the adsorption of heavy metal ions, electrochemical capacitors and sensors, oil purification, microbial fuel cells, and reverse osmosis membranes were among the potential uses for zeolite/graphene oxide composites that were investigated in earlier studies. The aforementioned applications show how versatile zeolite/graphene oxide composites are. In addition to summarizing earlier studies on the techniques for synthesizing graphene with common zeolites, this study has also taken historical data to demonstrate improvements in the use of zeolite/graphene composites in diverse industrial applications. There is, nevertheless, a lot of potential for the study of zeolite/graphene composites because the bulk of applications use zeolites and graphene oxide as distinct components. Again, this study has explored the composite potential of graphene with other materials in energy storage, fuel cracking and adsorption applications. This study provides a comprehensive review of the synergistic benefits of graphene composites and its future opportunities and challenges.
