5.2 Sol-Gel Method
87
rGO paper when sol-gel process parameters were set to 1-PrOH as a solvent, TeA
as a stabilizer, sol concentration of 0.2 M, deposition speed of 30 mm min
−1 , and
10 deposited layers. We aspire that this method of sandwiching of metal oxide and
GO paper into flexible electrodes will provide a new approach to the design of
flexible electrode for supercapacitor applications. Besides, shown in Fig. 5.4a, Wu
et al. controlled synthesized V 2 O 5 /MWCNT core/shell hybrid aerogels with different
MWCNT contents through a facile mixed growth and self-assembly methodology in
a sol-gel process (Wu et al. 2015). During the hydrolysis process, core/shell structure
V 2 O 5 coated MWCNTs and V 2 O 5 nanowires were obtained simultaneously through
in situ growth and preferred orientation growth, respectively. Then these two kinds
of 1D nanowires are self-assembled into 3D V 2 O 5 /MWCNT hybrid aerogels.
As a result of the expensiveness of the precursors, process, and non-Eco friendliness, the design and development of an economic as well as highly active nonprecious electrocatalyst for ethanol electro-oxidation is challenging In Fig. 5.4b,
