Effect of hybridization on the value-added activated carbon materials

Abstract

This paper provides a concise review of recent advances in activated carbon (AC) and its corresponding modified material. Topics covered in this work include the synthesis and characterization of AC as the feedstock materials, as well as the properties and applications of the subsequent hybrid material for different industries. Numerous research studies have since reported remarkable physical, chemical, thermal, conductivity, porosity, and mechanical (stiffness and strength) properties of AC in different types of multiple material matrices, including polymers, metals, and ceramics. The incorporation of AC particles into material matrices may result in the formation of an entire new class of advanced materials, due to the resulting strong interfacial bonds of the hybrid components. Although this requirement is no different from those that offer conventional hybrid materials, the scale of the reinforcement and filled phase of the AC has changed from micrometers to nanometers. This create opportunities to increase the potential applications of AC hybrid materials of the development of fundamentally unique new materials for in chemical conversion, environmental, and fuel storage applications.

Activated Carbon and Clay Pellets Coated with Hydroxyapatite for Heavy Metal Removal: Characterization, Adsorption, and Regeneration

“…AC has relatively high affinity towards Pb(II), Cd(II), Cu(II), Ni(II), and Zn(II) [6][7][8][9]. Application of AC in powder form in the adsorption process has some disadvantages, such as agglomeration and filtration difficulties due to very fine particles that form a dense filter layer in slurry phase operations [10]. Additionally, a huge volume of adsorbent is required in the adsorption process.…”

Surface and chemical characteristics of platinum modified activated carbon electrodes and their electrochemical performance

“…Although it is reported that the AC/metal composite may exhibit high transfer characteristics and effective catalytic/adsorptive properties [21,22], it is believed that the difficulty of keeping the metal in the zero-valent state on AC surface may be a reason for the limited number of papers. Especially the oxygen-containing surface functional groups on the AC surface have great influence on the oxidation of transition metals [23].…”

Supercritical hydrothermal synthesis of silver nanoparticles, composites, and their characterizations

“…SCW condition also allows the nanoparticles to deposit on a support surface and inside the pores in well-dispersed conditions [9]. Furthermore, carbonsupported metal oxides are of interest in an adsorption technique because porous activated carbon can be incorporated with metal oxides by various functional groups on the own surface, and it has a large specific surface area and pore distributions that are required for the removal of pollutants [10][11][12]. Due to these advantages, the use of activated carbon, often as a composite material with metal oxides, in wastewater treatment is increasing dramatically [13].…”
