This review covers the use of Prussian blue and its analogues as sacrificial templates adopted strategies to produce new materials with diverse compositions, structures morphologies.
MAX phases are etched using an ionic liquid-water mixture to produce titanium carbide MXenes. The process avoids the use of any acid. Hydrolysis fluorine-containing liquid leads selective removal Al, while is intercalated in-between transition metal layers.
Technologies for the effective and energy efficient removal of salt from saline media advanced water remediation are in high demand. Capacitive deionization using carbon electrodes is limited to highly diluted water. Our work demonstrates desalination performance silver/silver chloride conversion reaction by a ion rocking-chair mechanism. Silver nanoparticles used as positive while their chlorination into AgCl particles produces negative electrode such combination that enables very low cell...
Abstract MXene is investigated as an electrode material for different energy storage systems due to layered structures and metal‐like electrical conductivity. Experimental results show MXenes possess excellent cycling performance anode materials, especially at large current densities. However, the reversible capacity relatively low, which a significant barrier meeting demands of industrial applications.
