Electrochemical supercapacitor material based on manganese oxide: preparation and characterization

Recent Advancements in the Cobalt Oxides, Manganese Oxides, and Their Composite As an Electrode Material for Supercapacitor: A Review

“…To overcome such hindrances, recently, the researchers have been executing many new strategies, such as use of carbon containing materials for increasing the electrical conductivity and adopt the volume buffers for relaxing internal stresses (Yao et al, 2008;Sui et al, 2015). Manganese oxides have been prepared by various synthesis methods, such as pulse laser deposition method (Xia et al, 2011), hydrothermal method , electrochemical synthesis method (Jiang and Kucernak, 2002), redox deposition method (Bordjiba and Bélanger, 2009), successive hydrolysis-condensation method (Sawangphruk and Limtrakul, 2012), etc. Further, the detail of MnO2 synthesis and their supercapacitive performance are shown in Table 2.…”

Preparation and Characterization of Ordered Nanostructured Cobalt Films via Lyotropic Liquid Crystal Templated Electrodeposition Method

“…Furthermore, the shape of the CV curves reveals that the capacitance characteristic of Co is distinct from that of the electric double layer capacitance, which would produce a CV curve close to an ideal rectangular shape. Since electrolyte template and electrode resistance can distort current response at the switching potential and this distortion is dependent upon the scan rate, 30 the shape of the CV has changed with variation of the scan rate increased. These results indicate that the capacitance is mainly based on redox mechanism.…”

Screen-printed Dissolved Oxygen Sensor Based on Cerium Oxide-supported Silver Catalyst and Polydimethylsiloxane Film

“…Various metals, 2,5-7 metal complexes [8][9][10] and enzymes 11 have been widely studied as catalsts for oxygen reduction to improve the catalytic efficiency and to fabricate inexpensive oxygen sensors. Recently, the authors prepared a cerium oxide-supported silver (CeO2/Ag) catalyst, and reported that quasi-4 electron reduction occurs on the CeO2/Ag surface.…”
