“…Clearly, a fast adsorption process was observed within the first 20 min and adsorption capacity attained around 80% of the saturated state, followed by slow adsorption kinetics. It could be attributed to that there were numerous blank active sites on adsorbent at early stage, and fewer sites were available as the reaction processed [46]. Moreover, repulsive force may occur between anions of 2,4-D adsorbed on adsorbent and the ones in solution.…”

“…The type IV isotherm with H3 hysteresis loop indicates the prevalence of mesoporous characteristics (i.e. the sample contains pores with diameter within the range on 2 nm to 50 nm) of the Fe‐Mn‐Zr trimetal oxide nanocomposite and pore distribution is of non‐uniform nature with interconnection between them . The specific surface area of Fe‐Mn‐Zr trimetal oxide nanocomposite was found to be 143.01 m 2 /g and total cumulative pore volume was 0.0923 cm 3 /g.…”

A novel adsorbent, Fe‐Mn‐Zr metal oxide nanocomposite was synthesized and investigated for removal of methyl orange (MO) and eosin yellow (EY) dyes from binary dye solution. The magnetic nanocomposite has shown surface area of 143.01 m2/g and saturation magnetization of 15.29 emu/g. Optimization was carried out via response surface methodology (RSM) for optimizing process variables, and optimum dye removal of 99.26% and 99.55% were obtained for MO and EY dye, respectively with contact time 62 min, adsorbent dose 0.45 g/l, initial MO concentration 11.0 mg/l, and initial EY concentration 25.0 mg/l. A feed forward back propagation neural network model has shown better prediction ability than RSM model for predicting MO and EY dye removal (%). Adsorption process strictly follows Langmuir isotherm model, and enhanced adsorption capacities of 196.07 and 175.43 mg/g were observed for MO and EY dye, respectively due to synergistic effects of physicochemical properties of trimetal oxides. Surface adsorption and pore diffusions are the mechanisms involved in the adsorption as revealed from kinetic studies.

“…Graphene-CeO 2 nanocomposite with high catalytic activity was prepared by Srivastava et al 62 using hydrothermal method. Zhang et al 63 66 using solvothermal method and investigated its adsorbent and antimicrobial properties. The examination revealed that prepared nanocomposite had good adsorption efficiency regarding the removal of toxic heavy metal ions (Pb and Cd) and can also act as an efficient antimicrobial agent.…”

Nanocomposite material proves to be the best candidate to match today's technological need as fascinating properties can be achieved by combining two or more nanomaterials. Among various nanomaterials, graphene is able to stand out far ahead of all others because of its novel structure and exclusive characteristics. In particular, graphene-metal nanocomposites have attracted enormous interest for their prospective use in various fields, including electronics, electrical and energy-related areas. However, for the utmost use of potential of graphene, it has to be homogenously embedded into metal matrices. Thus, appropriate synthesis route is decisive to obtain graphene-metal nanocomposites with desired properties. This chapter will summarize the different synthesis routes of high-quality graphene-metal nanocomposites along with their current developments. one is the called matrix or binder which encloses and binds together fragments or fibres of the other material, termed as reinforcement. If one of the constituent materials of the composite is of nanometer dimension then the composite is called nanocomposite 1 and in most of the cases the nanomaterial are used as reinforcement material. Since the advent of nanomaterial several of them is used to synthesise nanocomposite, as nanomaterial possesses remarkable improvement in their properties compared to their bulk counterpart 2 . The inclusion of nanomaterial as the reinforcement in the parent matrix also significantly enhances the properties of the resulting nanocomposite 3 . Among the different nanomaterials graphene has emerged as one of the most prospective nanomaterials due to the unique combination of its exotic properties 4 . Based on the binder material graphene nanocomposite can be categorized as graphene metal/metal oxide nanocomposite 5 , graphene ceramic nanocomposite 6 , graphene semiconductor nanocomposite 7 and graphene polymer nanocomposite 8 . Among various nanocomposites, graphene-metal/metal oxide composites have attracted considerable attention because of their potential applications in energy 9 and health 10 -related areas.
