Special Issue Information

Dear Colleagues,

This Special Issue focuses on the application of functional nanomaterials for energy storage and environmental purification. The articles in this issue explore functional nanomaterials with special structures that can be leveraged to improve the efficiency and sustainability of energy storage and consumption, as well as to address pressing environmental challenges such as pollution and climate change. Topics include the development of new nanomaterials for sustainable energy storage technologies, such as secondary batteries and supercapacitors, as well as their potential applications in water purification, carbon capture, VOC elimination, and other environmental remediation efforts. The Special Issue highlights the in-depth understanding of the relationship between the structure of functional nanomaterials and their electrochemical energy storage properties, activities, adsorption and catalytic characteristics, evaluation of device configuration, etc. We invite leading groups in the field to contribute their original research articles and review articles to promote the progress in the discipline.

Currently, exploring high-capacity, stable cathode materials remains a major challenge for rechargeable Aluminum-ion batteries (AIBs). As an intercalator for rechargeable AIBs, Al3+ produces three times the capacity of AlCl4− when the same number of anions is inserted. However, the cathode material capable of producing Al3+ intercalation is not a graphite material with AlCl4− intercalation but a transition metal sulfide material with polar bonding. In this paper, the insertion mechanism of Al3+ in 3R-MoS2 is investigated using first-principles calculations. It is found that Al3+ tends to insert into different interlayer positions at the same time rather than occupying one layer before inserting into another, which is different from the insertion mechanism of AlCl4− in graphite. Ab initio, molecular dynamics calculations revealed that Al3+ was able to stabilize the insertion of 3R-MoS2. Diffusion barriers indicate that Al3+ preferentially migrates to nearby stabilization sites in diffusion pathway studies. According to the calculation, the theoretical maximum specific capacity of Al3+ intercalated 3R-MoS2 reached 502.30 mAg h−1, and the average voltage of the intercalation was in the range of 0.75–0.96 V. Therefore, 3R-MoS2 is a very promising cathode material for AIBs. Full article

The search for efficient, environmentally friendly adsorbents is critical for purifying dye wastewater. In this study, we produced a first-of-its-kind effective biomimetic amorphous calcium carbonate (BACC) using bacterial processes and evaluated its capacity to adsorb a hazardous organic cationic dye—methylene blue (MB). BACC can adsorb a maximum of 494.86 mg/g of MB, and this excellent adsorption performance was maintained during different solution temperature (10–55 °C) and broad pH (3–12) conditions. The favorable adsorption characteristics of BACC can be attributable to its hydrophobic property, porosity, electronegativity, and perfect dispersity in aqueous solution. During adsorption, MB can form Cl-Ca, S-O, N-Ca, and H-bonds on the surface of BACC. Since BACC has excellent resistance to adsorption interference in different water bodies and in real dye wastewater, and can also be effectively recycled six times, our study is an important step forward in dye wastewater treatment applications.
