Abstract
Transition Metal Dichalcogenides Transition metal dichalcogenides (sulfides) have a layered structure. ReS2 and FeS2 in the form of composites with carbon nanotubes and 3D graphene (3DG)-like material are used as electrochemical capacitor electrodes. Sulfates (Li, Na) serve as electrolytic medium. Catalytic effect of Re for hydrogen evolution reaction plays a crucial role in limiting capacitor voltage to 0.8 V whereas capacitor with 3DG/FeS2 can reach 1.5 V. More information can be found in article number 2006821 by Elzbieta Frackowiak and co-workers.
