Mesoporous Activated Carbon as a Novel Substrate for MnO2
Disciplines
Inorganic Chemistry | Materials Chemistry
Abstract (300 words maximum)
In recent years MnO2 has become an ideal material for use in aqueous Zinc ion batteries and aqueous capacitors due to its ease of synthesis, cost, and high performance. As a capacitor, the performance is largely due to manganese dioxide’s pseudo-capacitance behavior rather than high surface area electric double layer (EDLC) effects. Activated carbon presents an ideal substrate due to its high conductivity and surface area characteristics. To allow for the efficient formation of MnO2, the pores of the activated carbon are expanded using KOH activation and hydrothermal acid etching. In this study, treated activated carbon is used as a substrate for a thin film of MnO2 to increase the effective surface area of the MnO2 layer for higher performance and rate capabilities. All the synthesized materials will be characterized using powder XRD, N2 physisorption, cyclic voltammetry, EIS, EDS, and SEM.
