“…In addition, some cylindrical object can be observed in the 40ACGC sample, which may be newly formed zeolite during the process of geopolymerization. Similar formation of zeolite in geopolymers has been reported by the previous literature 42,43 . Figure 5 shows the EDS mapping results of the 40ACGC sample, in which the AC particles are inlaid in the geopolymer matrix.…”

“…G exhibits limited N 2 uptake, suggesting its low specific surface area (17.47 m 2 /g) and pore volume (.0008 cm 3 /g). Indeed, geopolymers possess zeolite‐like structures but they do not exhibit satisfying zeolitic capabilities in most cases, owing to their limited porosity 42,43 . Herein, after adding AC, the pore content and specific surface area of the geopolymer are markedly extended.…”

An activated carbon‐geopolymer composite (ACGC) was prepared by using fly ash as raw materials via a simple geopolymerization process for treating the Pb(II) contaminant in wastewater and soil. The phase composition, microtopography, pore structure, and surface groups of the composites were studied by X‐ray diffractometer, field emission scanning electron microscopy, X‐ray photoelectron spectroscopy, N2 adsorption‐desorption isotherm, and Fourier transform infrared spectroscope. It was discovered that there was a synergistic effect between geopolymer matrix and activated carbon (AC), that is, addition of AC particles could increase the pores in geopolymer while strong alkalis condition provided by geopolymer enhanced the contents of oxygenic groups of AC. When the composite was used as the adsorbent, the sample containing 20 wt% AC (40ACGC) showed the maximum adsorption capacity (319.72 mg/g), and its adsorption isotherm fitted the Langmuir model well, suggesting the monolayer adsorption of Pb2+ on the 40ACGC. The kinetics of Pb2+ adsorption on the 40ACGC belonged to the pseudo‐second‐order model, indicating that Pb2+ adsorption on the composite followed chemical adsorption. In addition, the 40ACGC sample showed excellent stabilization performance for Pb2+ in soil. This work offered a new thinking to the application of geopolymers into remediation of heavy metal‐polluted soil.

“…Through investigation, it was found that the crustal abundance of sodium metal (2.74%) is more than 420 times that of lithium metal (0.0065%), which is rich in resources and evenly distributed worldwide [ 24 , 25 , 26 ]. Moreover, the two elements are of the same main group and have similar physical and chemical properties and similar electrochemical behaviors, and many technologies applied to lithium-ion batteries can also be applied to sodium-ion batteries [ 27 , 28 , 29 , 30 , 31 , 32 , 33 ]. Sodium-ion batteries have attracted wide attention as a substitute for lithium-ion batteries [ 34 , 35 , 36 , 37 , 38 ].…”

The Progress of Hard Carbon as an Anode Material in Sodium-Ion Batteries

When compared to expensive lithium metal, the metal sodium resources on Earth are abundant and evenly distributed. Therefore, low-cost sodium-ion batteries are expected to replace lithium-ion batteries and become the most likely energy storage system for large-scale applications. Among the many anode materials for sodium-ion batteries, hard carbon has obvious advantages and great commercial potential. In this review, the adsorption behavior of sodium ions at the active sites on the surface of hard carbon, the process of entering the graphite lamellar, and their sequence in the discharge process are analyzed. The controversial storage mechanism of sodium ions is discussed, and four storage mechanisms for sodium ions are summarized. Not only is the storage mechanism of sodium ions (in hard carbon) analyzed in depth, but also the relationships between their morphology and structure regulation and between heteroatom doping and electrolyte optimization are further discussed, as well as the electrochemical performance of hard carbon anodes in sodium-ion batteries. It is expected that the sodium-ion batteries with hard carbon anodes will have excellent electrochemical performance, and lower costs will be required for large-scale energy storage systems.
