“…With this approach some irreversible behavior in the cathodic side can be easily identified during the first few cycles: the reason is the low hydrogen evolution overpotential on SWCNTs, as already reported in Ref. [13]. Moreover, the shape of the curve-especially the one for high SWCNT loadings-suggests the presence of a slow ion sorption, leading to an additional specific charge at lower specific currents.…”

Wearable electronics offer the combined advantages of both electronics and fabrics. In this article, we report the fabrication of wearable supercapacitors using cotton fabric as an essential component. Carbon nanotubes are conformally coated onto the cotton fibers, leading to a highly electrically conductive interconnecting network. The porous carbon nanotube coating functions as both active material and current collector in the supercapacitor. Aqueous lithium sulfate is used as the electrolyte in the devices, because it presents no safety concerns for human use. The supercapacitor shows high specific capacitance (~70-80 F·g -1 at 0.1 A·g -1) and cycling stability (negligible decay after 35,000 cycles). The extremely simple design and fabrication process make it applicable for providing power in practical electronic devices.

“…Owing to structural and chemical properties the CNTs and CNFs are regarded as promising electrode materials for chemical power sources such as lithium-ion cells [1,2], supercapacitors [3][4][5] and reversible hydrogen reservoirs [6][7][8][9][10][11][12][13]. During the last decade the ability of the mentioned carbon materials for storing hydrogen has attracted a great interest due to the possibility of modification of their physicochemical properties allowing the increase of hydrogen sorption.…”

“…There are several reports which have used Pd as a catalyst for electrochemical hydrogen production [35,36], but this metal is expensive, therefore, in this work the loaded Pd on the catalyst is low. Also there are some reports which have used carbon nanotubes in the electrode composition for electrochemical HER [37][38][39]. In addition, there are several reports which have applied the MOF [22][23][24][25], Pd [40,41] and SWCNT [37,38] as adsorbent for hydrogen, and one of the famous mechanisms for electrochemical HER in acidic media is based on hydrogen adsorption on the electrode surface in the rate determining step (Volmer reaction) [42].…”

There are very rare reports on using metal-organic framework (MOF) catalysts for electrochemical hydrogen production. In this study, a composite of palladium, single-walled carbon nanotube (SWCNT) and was synthesized by hydrothermal method, and its application as electrocatalyst in carbon paste electrode (CPE) structure for hydrogen production was studied. Scanning electron microscopy, X-ray diffraction, Brunauer-Emmett-Teller and thermal gravimetric analysis were used to characterize Pd/ SWCNTs@MOF-199 catalyst. The performance of the proposed modified CPE for electrochemical hydrogen production was studied by cyclic voltammetry, linear sweep voltammetry, electrochemical impedance spectroscopy and chronoamperometry techniques. The effect of solution pH and the amount of binder and catalyst in the paste composition were investigated. The results showed that the CPE modified with Pd/SWCNTs@MOF-199 reveals better catalytic characteristics such as highest catalytic activity and lowest onset potential compared to CPE and CPE modified with MOF-199 for hydrogen production in aqueous solution.
