Drexel researchers demonstrate intercalation of MXenes with a variety of ions; high volume

Drexel researchers demonstrate intercalation of MXenes with a variety of ions; high volumetric capacitance 28 September 2013 Researchers at Drexel University with colleagues in France have demonstrated that titanium carbide (Ti3 C2 ) “MXene” compounds—exfoliated 2D carbide and carbonitride nanosheets that are structurally similar to graphene, where M represents transition metals, and X is either C or/and N (earlier post )—support the spontaneous intercalation of cations from aqueous salt solutions. A variety of cations, including Na+ , K+ , NH4 + , Mg2 + , and Al3 + , can also be intercalated electrochemically, offering capacitance in excess of 300 farads per cubic centimeter (much higher than that of porous carbons). A paper on their work is published in Science . About three years ago, Dr. Michel W. Barsoum and Dr. Yury Gogotsi, professors in Drexel’s College of Engineer...
