“…We compared the adsorption performance of the present adsorbent with that of other adsorbent materials reported in the literature. − As shown in Table , CNT/Co@N–C-525 synthesized in this study exhibited a stronger adsorption capacity and greater stability compared to those of other adsorbent materials reported in the literature. Therefore, CNT/Co@N–C-525 may be a suitable adsorbent for the practical applications of dye wastewater treatment.…”

In this work, magnetic nitrogen-doped carbon composites decorated with carbon nanotubes (CNT/Co@N−C) were successfully prepared by carbonizing ZIF-67(Co) and melamine with a ZIF-67(Co)/melamine material synthesized in situ at 525 °C under an inert atmosphere. To improve the malachite green removal performance of the adsorbent, calcination temperatures and mass ratios of the ZIF-67(Co)/melaminederived CNT/Co@N−C materials were optimized. The malachite green removal performance was evaluated based on various experimental parameters including adsorbent dosage, pH, contact time, and salinity. The results showed that pH and salinity had a small effect on the adsorption process of CNT/Co@N−C materials, thus providing a possibility for practical application in water purification. The adsorption of malachite green onto the CNT/Co@N−C material was consistent with the Langmuir isothermal model and the pseudo-second-order model, and the maximum malachite green adsorption of the material was 3881.30 mg/g. The results also suggested that the adsorption was a monolayer chemisorption process that occurred through electrostatic and π−π stacking interactions. Finally, the recyclability, magnetic properties, high adsorption performance, and high stability of CNT/ Co@N−C materials suggest that the materials are a promising adsorbent that can be employed in the removal of malachite green. The present work provides an idea for the synthesis of magnetic carbon nanotubes modified with nitrogen-doped carbon materials derived from metal−organic frameworks (MOFs).

“…The thermodynamic studies determine the adsorption feasibility and physicochemical parameters such as Gibbs free energy, entropy change, and enthalpy change. These equations are shown below The observed thermodynamic parameters are summarized in Table 3 and 47,65,66 The negative value of DS1 for both adsorbates signifies the decreased disorder and degree of freedom at the adsorbate-adsorbent interface. The negative DG1 at all temperatures of INH implies the adsorption process is spontaneous and favourable and it increases with the increase in temperature.…”

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.
