Synthesis and characterization of mesoporous Mn–Ni oxides for supercapacitors

A novel interfacial synthesis of MnO–NiO–reduced graphene oxide hybrid with enhanced pseudocapacitance performance

“…4b) is divided into four functional groups: the C-C bond at 284. 51 groups, corresponding well to the FTIR results. 39,46 The binding energies for Mn 2p 3/2 and Mn 2p 1/2 are found to be 641.5 and 653.4 eV (Fig.…”

High‐Performance Fabric‐based Electrochemical Capacitors Utilizing the Enhanced Electrochemistry of PEDOT:PSS Hybridized with SnO2 Nanoparticles

“…The enhanced capacitance of SnO 2 /PEDOT:PSS is also evident in the plot of specific capacitance vs. scan rate (Figure 4(d)). It was reported that SnO 2 nanowires, 19 porous NiO nanofibers, 21 and irregular mesoporous agglomerates of Mn-Ni oxides 22 achieved high specific capacitances. In addition, Figure 4(d) indicates that the specific capacitance increased as the scan rate decreased.…”

“…Similar strategies were already employed for SnO 2 or metal oxides–based supercapacitor electrodes to enhance their capacitive performances. It was reported that SnO 2 nanowires, porous NiO nanofibers, and irregular mesoporous agglomerates of Mn–Ni oxides achieved high specific capacitances. Hence, similar modification of the nanostructures or porosity of SnO 2 would enhance the capacitive performances of SnO 2 /PEDOT:PSS electrodes significantly.…”

Flower-like NiO structures: Controlled hydrothermal synthesis and electrochemical characteristic

“…In particular, considerable research efforts have been devoted to the use of nickel oxide [24][25][26][27][28] for super capacitors, due to its good pseudocapacitive behavior, practical availability, environmentally benign nature and lower cost compared to the state-of-the-art supercapacitor material RuO 2 . Currently, the extension of soft or hard templating procedures to the formation of porous NiO with larger specific surface areas has attracted great interest.…”
