Designed synthesis of SiC nanowire-derived carbon with dual-scale nanostructures for supercapacitor applications

Abstract

A simple approach has been designed for the synthesis of mesoporous silicon carbide-derived carbon nanowires (SiC-CDC NWs) for supercapacitor applications.

Continuous electrodeposition of silicon and germanium micro⁄nanowires from their oxides precursors in molten salt

“…Cyclic voltammetry (CV) study was performed by using a graphite rod working electrode in the SiO 2 and/or GeO 2 saturated CaCl 2 -CaO molten salt system. More similar experimental details can be found in our previous work [25][26][27] .…”

“…However, continuous production of Si and Ge nanostructures still remains a challenge. In recent years, molten salt electrochemical process has been intensively developed for various micro/nanostructured materials syntheses [12][13][14][15][16][17][18][19][20][21][22][23][24][25] . In particular, molten salt electrochemical process shows promising potential for the direct synthesis of Si and Ge nanostructures from their oxides precursors [ 13-16 , 19-23 ].…”

Controllable conversion of rice husks to Si/C and SiC/C composites in molten salts

“…The high-resolution TEM image shows distinct lattice fringes with an interlayer spacing of 0.25 nm, attributing to the (1 1 1) crystal plane of cubic b-SiC (Fig. 2f) [32]. Formation of SiC nanowires is further manifested by the homogeneous distribution of Si and C in the elements mapping images (Fig.…”

“…In addition, anodic evolution of corrosive Cl 2 can be avoided, replaced by releasing CO 2 on a graphite anode or O 2 on an inert anode [27]. However, formation of unpleasant SiC in CaCl 2 -based molten salt largely restricts the conversion of RHs to Si/C composites [8,22,23,[32][33][34].…”

Arc erosion behavior of TiB2/Cu composites with single-scale and dual-scale TiB2 particles

“…Lee presented a trans- parent electrode based on a dual-scale silver nanowire (AgNW) percolation network embedded in a flexible substrate to demonstrate a significant enhancement in the effective electrical area by filling the large percolative voids present in a long/thick AgNW network with short/thin Ag-NWs [20]. Zou reported a simple strategy for electrosynthesis of silicon carbide nanowires (SiC NWs)-derived carbon with dual-scale nanostructures for high performance supercapacitors [21]. The above research results provide a new idea for the design and development of high performance copper matrix composites.…”
