Based on a porous carbon electrode, capacitive deionization (CDI) is promising desalination technology in which ions are harvested and stored an electrical double layer.
The demand for fresh water has been increasing, caused by the growing population and industrialization throughout world. In this study, we report a capacitive-based desalination system using Prussian blue materials in rocking chair battery, which is composed of sodium nickel hexacyanoferrate (NaNiHCF) iron HCF (NaFeHCF) electrodes. system, ions are removed not only charging steps but also discharging steps, it possible to treat actual seawater with because material high charge capacity...
The demand for lithium has greatly increased with the rapid development of rechargeable batteries. Currently, main resource is brine lakes, but conventional recovery process time consuming, inefficient, and environmentally harmful. Rechargeable batteries have been recently used recovery, consist iron phosphate as a cathode. These feature promising selectivity between sodium, they suffer from severe interference coexisting magnesium ions, an essential component brine, which prompted further...
Recently, black-colored TiO2 NTA (denoted as black NTA) fabricated by self-doping of with the amorphous phase led to significant success a visible-light-active photocatalyst. This enhanced photocatalytic activity is largely attributed higher charge carrier density an effect electrochemical resulting in optical absorbance and lower transport resistance. Nevertheless, potential for other applications, such supercapacitor oxidant-generating anode, has not been fully investigated. Here, we...
Abstract Securing lithium resources is an emerging issue owing to the widespread use of lithium‐ion batteries. Recently, electrochemical recovery method based on principle a battery using lithium‐capturing electrode and silver as negative was proposed meet increased demand for lithium. However, high cost one hindrance facilitating practical this recovery. In study, zinc, which has low price, large capacity, stable redox potential, alternative material. Using LiMn 2 O 4 –zinc (LMO‐Zn) system,...
A novel electrochemical system comprising λ-MnO<sub>2</sub> and BDD is proposed for simultaneous recovery of lithium decomposition organic pollutants.
Capacitive deionization (CDI) is considered an alternative desalination technology due to its easy operation, high energy efficiency, and environmentally friendly process. However, a separate regeneration step required in typical CDI technologies that releases the absorbed ions on electrodes which results inefficient cost-intensive This study proposed novel system referred as rocking-chair capacitive (RCDI) has continuous brackish water process consists of pair Nafion-coated activated carbon...
Both the origin and mechanism of improvement in electrochemical performances post-thermal treated LiCoO2 as a cathode material for lithium ion batteries are investigated through high-quality characterization. X-ray diffraction transmission electron microscopy measurements revealed that high temperature sintering results Li deficiency consequent formation spinel LixCo2O4. The slow quenching allows two phases LixCo2O4 to intermix, whereas treatment at 800 °C separation phase surface LiCoO2....
The objective of this study was to investigate the effect doping level blue and black TiO<sub>2</sub> NTAs on their electrochemical properties, including capacitive oxidant-generating properties.
Abstract Although 2D|3D has shown potential for application in multifunctional devices, the principle of operation multifunction devices (SOLAR Cell‐LED: SOLED) not yet been revealed. However, most studies have reported that only one auspicious characteristic. Here this study SOLED are monitored and investigated a heterostructure with multidimensional perovskite. It is fond perovskite interface induces carrier transmission from interface, increasing density electrons holes, their...
Various lithium recovery technologies have been developed as securing resources has become increasingly important. Among these technologies, the electrochemical (ELR) system is a rapid and eco-friendly extraction method that studied recently. In this paper, an ELR using spinel-type LiMn2O4 (LMO) briefly reviewed. As LMO electrodes high Li+ selectivity stability compared to other battery cathodes, they widely used positive for system. This paper summarizes proposal, electrode modification,...
