Graphene oxide (GO), a single sheet of graphite oxide, has shown its potential applications in electrochemical energy storage and conversion devices as a result of its remarkable properties, such as large surface area, appropriate mechanical stability, and tunability of electrical as well as optical properties. Furthermore, the presence of hydrophilic functionalities on basal and edge planes induces other relevant properties, which make GO an attractive material for electrochemical applications. On account of having structural diversity and enhanced overall crucial properties, GO and its composites have attracted much attention in contribution of energy storage devices, such as batteries, supercapacitors, and energy conversion devices, such as fuel cells and water electrolyzers. Previous review reports demonstrated the individual applications of GO or reduced graphene oxide (RGO) in either of the electrochemical energy devices. The present review highlights all of the recent developments of GO and RGO in both the energy storage and conversion devices along with the recent synthesis methodologies, which are crucial to unveil all of the outperforming properties of GO and RGO. The transition in the synthesis of GO with various chemical methods, including the Brodie and improved Hummers methods, to electrochemical approaches have been described with recent developments as well as highlights of the importance of electrochemical energy in the synthesis of GO. Utilization of GO in energy storage applications predominantly as electrodes and electrolytes and membranes in energy conversion devices further diversify its multiple applicability as a result of its variable functional properties. Multiple energy storage devices, such as Li-ion, Na-ion, Li−S, and flow batteries and supercapacitors, have shown the enhanced performance with the introduction of GO and RGO. Furthermore, GO has also shown excellent applicability in energy conversion devices, such as protonexchange membrane fuel cells, methanol fuel cells, and water electrolyzers, which have also been discussed in this review. This review further summarizes the recent synthesis methodologies of GO and RGO along with their importance in electrochemical energy devices with allied challenges and future perspectives.

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.

The performance of supercapacitors strongly depends on the electrochemical characterizations of electrode materials. Herein, a composite material consisted of polypyrrole (PPy) and multilayer graphene-wrapped copper nanoparticles (PPy/MLG-Cu NPs) is fabricated on a flexible carbon cloth (CC) substrate via two-step synthesis process for supercapacitor application. Where, MLG-Cu NPs are prepared on CC by one-step chemical vapor deposition (CVD) synthesis approach; thereafter, the PPy is further deposited on the MLG-Cu NPs/CC via electropolymerization. The related material characterizations of PPy/MLG-Cu NPs are well investigated by scanning electron microscopic (SEM), high resolution transmission electron microscopy (HR–TEM), Raman spectrometer and X-ray photoelectron spectroscopy (XPS); the electrochemical behaviors of the pertinent electrodes are studied by cyclic voltammogram (CV), galvanostatic charge/discharge (GCD) and electrochemical impedance spectroscopy (EIS) measurements. The flexible electrode with PPy/MLG-Cu NPs composites exhibits the best specific capacitance of 845.38 F g-1 at 1 A g-1, which is much higher than those of electrodes with PPy (214.30 F g-1), MLG-Cu NPs (6.34 F g-1), multilayer graphene hollow balls (MLGHBs; 52.72 F g-1), and PPy/MLGHBs (237.84 F g-1). Finally, a supercapacitor system consisted of four PPy/MLG-Cu NPs/CC electrodes can eﬃciently power various light-emitting diodes (i.e., red, yellow, green, and blue lighs), demonstrating the practical application of PPy/MLG-Cu NPs/CC electrode.
