Wet chemical synthesis of Gd+3 doped vanadium Oxide/MXene based mesoporous hierarchical architectures as advanced supercapacitor material

Iron/vanadium co-doped tungsten oxide nanostructures anchored on graphitic carbon nitride sheets (FeV-WO3@g-C3N4) as a cost-effective novel electrode material for advanced supercapacitor applications

“…CV curves remained uniform along y-axis with the increase in scan rate, and it also shows the good reversibility of redox processes. 82 Specic capacitance of all the prepared electrodes at different scan rates i.e., 5 mV s −1 to 100 mV s −1 was calculated by the following eqn (4): 83,84…”

Hydrothermal Self-Assembly of α-MnSe-Loaded Honeycomb-Like Biomimetic Ti3C2Tx/Graphene Aerogel Microstructure (α-MnSe/Ti3C2Tx/rGO) as Efficient Electrode Material for Energy Storage Application

“…The integrated CV curve area and current response were in order of MnSe/TCGA > MnSe/GA > MnSe, which apparently indicates that MnSe/TCGA possesses a higher charge storage capacity compared to its counterparts. The logical argument for this could be the high conductivity, attributable to the TCGA backbone and the larger surface area of MnSe/TCGA than MnSe/GA and MnSe. , Though no clear oxidation–reduction peaks were observed through the voltammograms of the three samples, they deviate from the ideal EDLC rectangular shape with surge current extremes, recommending the presence of redox reactions of Mn 2+ ions. , The redox reactions that occur in the bulk and on the surface of MnSe in the prepared electrodes are described by eqs and : MnSe + N a + + e − ↔ M n normalS normale − N a + ( M n S e ) surface + N a + + e − ↔ ( normalM normaln normalS normale − N a ) surface …”

Applications of X‐Ray‐Based Characterization in MXene Research

“…[ 98 ] Also, EDX studies have difficulty in distinguishing impurities from atmosphere or during sample synthesis. [ 99–101 ]…”

“…[98] Also, EDX studies have difficulty in distinguishing impurities from atmosphere or during sample synthesis. [99][100][101] EDX analysis can also be used alongside TEM to achieve high resolution and local elemental information. [102,103] For example, Shen et al [104] applied the high-angle annular dark field (HAADF) scanning transmission electron microscopy (STEM) and the associated EDX elemental mapping to study the microstructure of functionalized MXene layers at a 40 nm scale.…”
