Ultraporous palladium on flexible graphene-coated carbon fiber paper as high-performance electro-catalysts for the electro-oxidation of ethanol

High-Performance Supercapacitor of Functionalized Carbon Fiber Paper with High Surface Ionic and Bulk Electronic Conductivity: Effect of Organic Functional Groups

“…To further confirm that the carboxylic group plays a vital role to the enhancement of areal capacitance of the f-CFP, the oxygen containing groups i.e., -COOH has been changed to amide groups i.e., CFP-CONHCH 2 CH 2 NH 2 namely f-CFP(EDA) and CFP-CONHCH 2 CH 2 CH 2 CH 3 namely f-CFP(BTM) by using simple dehydrogenation reactions (8)(9) above. CVs of f-CFP(EDA) and f-CFP (BTM) in 1 M H 2 SO 4 at a scan rate of 10 mV/s in Fig.…”

“…On the other hand, carbon-based current collector such as CFP is rather stable in all electrolytes [9][10][11][12][13]. CFP has many advantages suitably to be used as the conductive substrate or current collector including high flexibility, corrosive resistance, porosity, and conductivity.…”

“…However, CFP consisting of sp 2 carbon fiber (90-95 wt.%) and adhesive material PTFE (5-10 wt.%) can be used only as a conductive current collector since it cannot store charge and its hydrophobic surface in nature, which cannot adsorb/absorb the aqueous electrolyte. CFP is therefore used as the conductive substrate and/or current collectors of the supercapacitors and fuel cells [9][10][11][12][13].…”

Intrinsically Stretchable Fuel Cell Based on Enokitake‐Like Standing Gold Nanowires

“…Despite the development of commercial paper batteries, these devices are not stretchable. In this context, carbon fiber paper or carbon cloth, [25,26] graphene paper, [27] and nickel foam [28] have been successfully utilized to fabricate flexible methanol or ethanol fuel cells. [16,17] To date, some biofuel cell based stretchable energy devices have been developed to power wearable electronic devices.…”

“…[22,23] In contrast, methanol or ethanol based fuel cells have been shown to offer a much higher efficiency and reliability [24] because they are not influenced by external biological environments. In this context, carbon fiber paper or carbon cloth, [25,26] graphene paper, [27] and nickel foam [28] have been successfully utilized to fabricate flexible methanol or ethanol fuel cells. In this context, carbon fiber paper or carbon cloth, [25,26] graphene paper, [27] and nickel foam [28] have been successfully utilized to fabricate flexible methanol or ethanol fuel cells.…”
