Annealed Mn–Fe binary oxides for supercapacitor applications

Highly effective nickel sulfide counter electrode catalyst prepared by optimal hydrothermal treatment for quantum dot-sensitized solar cells

“…A low V oc or FF of the QDSSC always implies the significant recombination of excited electrons with the oxidized species at the electrode/electrolyte interface. For the polysulfide electrolyte, the lower hole-recovery rate of polysulfide leads to a higher probability for charge recombination and results in low V oc and FF [53].…”

Preparation of novel TiO 2 quantum dot blocking layers at conductive glass/TiO 2 interfaces for efficient CdS quantum dot sensitized solar cells

“…Polysulfide electrolyte was prepared with a similar method reported by Y. L. Lee et al [19]. The mixed solvents containing methanol and deionized water with volume ratio of 7:3 was used to prepare polysulfide electrolyte.…”

Application of Nanocomposites for Supercapacitors: Characteristics and Properties

“…Kim et al [2] also found that annealing of the nanocomposites can affect their capacitance: transition from amorphous to a crystalline structure occurred at high temperature (400 ºC) reduces the specific capacitance. Binary Mn-Fe oxide was electroplated on graphite substrates by Lee et al [3] at a constant applied potential of 0.8V vs. SCE in a mixed plating solution of Mn(CH 3 COO) 2 and FeCl 3 . The electrochemical behaviours of the as-deposited and the annealed mixed oxide nanocomposites were characterized by cyclic voltammetry in 2M KC1 solution.…”

“…For example, GN-CeO 2 nanocomposite was prepared by adding KOH solution dropwise into a Ce(NO 3 ) 3 aqueous solution in the presence of 3D GN material, followed by filtering, and drying. The GN-SnO 2 /CNTs nanocomposite was synthesized by ultrasonicating the mixture of chemically functionalized GN and SnO 2 -CNTs in water.…”
