CF4 plasma-treated porous silicon nanowire arrays laminated with MnO2 nanoflakes for asymmetric pseudocapacitors

Nanomaterial with Core–Shell Structure Composed of {P2W18O62} and Cobalt Homobenzotrizoate for Supercapacitors and H2O2-Sensing Applications

“…Electrode materials are at the heart of the research on these two types of supercapacitors. The electrode materials of PCs are mostly metal oxides [ 5 ], such as RuO 2 [ 6 ], MnO 2 [ 7 ], WO 3 [ 8 ] and MoO 3 [ 9 ], which are characterized by the ability to store charges on the electrode surface through redox reactions, in addition to the formation of electric double-layers through ion adsorption. They have the advantages of a high specific capacitance and high energy density.…”

Solution-processable hierarchical SiNW/PEDOT/MnOx electrodes for high-performance supercapacitors

“…Nevertheless, because of the rapid oxidation of the silicon surface, it is reported that the SiNW/MnO x hetero-structure synthesized by directly growing MnO x on 3D silicon has to be measured in a non-aqueous or an ionic liquid-based electrolyte. 34,35 Because the electrolytes are toxic, expensive, and have low-ionic conductivity, the electrochemical performances as well as the applicability of the resultant SCs are limited. To overcome these problems, the silicon surface is decorated with a highly conductive layer, such as porous carbon, 36 graphene, 37 and TiN, 38 at elevated temperatures where the high conductivity layer acts as the current collector and 3D silicon serves as the scaffold of the electrode.…”

Fabrication of p-type silicon nanowire array based photoelectrodes for the efficient photoelectrocatalytic reduction of CO2 to fuels and chemicals

“…59,60 The p-type Si nanowire arrays (SiNWs) are the one-dimensional nanostructures of p-type Si, which has better properties than bulk Si, such as the photoelectric effect and other optical properties, high surface activity, high electron transport characteristics, high stability and so on. [61][62][63][64][65] SiNWs have been widely used in the luminescent material and other research elds. In recent years, SiNWs have been widely reported in the application for the photoelectrocatalytic reduction of CO 2.…”
