“…The lowest ohmic resistance was obtained from the same electrode. This result when compared to the literature, Cu@Zn electrode lower than [26,27] SEM micrographs of CuFe, CuZn and Cu@Zn are given in Fig 4. When the micrograph taken from the surface of the CuFe electrode is examined, it is observed that there is a nonporous pile stacked adjacent to each other on the surface (Fig 4a). In Fig.…”

The different coatings with high hydrogen evolution reaction (HER) durability activity were prepared by electrodeposition. Iron, copper and zinc alloys were deposited on graphite electrode. The binary coating prepared on the graphite electrode. Zinc alloys were etched in alkaline solution to produce a porous and electrocatalytic surface suitable for use in the HER. The scanning electron microscopy (SEM) was used for surface characterization. Electrolysis was carried out in 1.0 M KOH solution by DC power supply. Cathodic current-potential curves, electrochemical impedance spectroscopy and cyclic voltammetry measurements were performed for chemical characterization. The experimental results show that the etching zinc alloys have compact and porous structures with good physical stability in comparison with other deposit for HER.

“…Three surfactants, namely Triton X-100, cetyltrimethylammonium bromide (CTAB), and sodium dodecyl sulfate (SDS), were used as protective agents for CuNPs, and CuNPs-nanocarbon hybrid materials were successfully prepared. The hybrid material prepared with SDS as the protective agent exhibited the best electrochemical activity [36]. Amorphous carbon and graphene-based materials have also been used in many studies to reduce the agglomeration of CuNPs [37,38].…”

Through the use of organic/inorganic hybrid dispersants—which are composed of polymeric dispersant and two-dimension nanomaterial graphene oxide (GO)—copper nanoparticles (CuNPs) were found to exhibit nano stability, air-stable characteristics, as well as long-term conductive stability. The polymeric dispersant consists of branched poly(oxyethylene)-segmented esters of trimellitic anhydride adduct (polyethylene glycol−trimethylolpropane−trimellitic anhydride, designated as PTT). PTT acts as a stabilizer for CuNPs, which are synthesized via in situ polymerization and redox reaction of the precursor Cu(CH3COO)2 within an aqueous system, and use graphene oxide to avoid the reduction reaction of CuNPs. The results show that after 30 days of storage the CuNPs/PTT/GO composite film maintains a highly conductive network (9.06 × 10−1 Ω/sq). These results indicate that organic/inorganic PTT/GO hybrid dispersants can effectively maintain the conductivity stability of CuNPs and address the problem of CuNP oxidation. Finally, the new CuNPs/PTT/GO composite film was applied to the electrocardiogram (ECG) smart clothes. This way, a stable and antioxidant-sensing electrode can be produced, which is expected to serve as a long-term ECG monitoring device.

“…In addition, some surfactants possess amphiphilic property, This series of molecules can generate thermodynamically stable gathers of intrinsically nano-scale both in solution and at the solid liquid interphases (Lee et al, 2019;Liu et al, 2019). Surfactants have a unique ability to self-organize at interface or in solution, modify interfacial properties and enhance the compatibility between materials of very different characteristics (Carswell et al, 2003;Hosseini et al, 2016).…”

Solvothermal method is a very common synthetic method in the preparation of catalysts for the hydrogen evolution reaction (HER) of H 2 O decomposition. Since a certain surfactant can be added to the solvothermal solvent, the crystal particle growth process can be changed to obtain catalysts with different morphologies. We synthesized a series of nickel-manganese oxides (NiMnO) by adding different amounts of Polyethylene glycol (PEG) using the solvothermal method. Structure characterizations exhibit that NiMnO catalyst prepared with different PEG additions have different morphologies. The NiMnO catalyst prepared by adding 3 g of PEG possesses abundant petal-like scales, it brings a large specific surface area, high reaction efficiency, and has the best electrocatalytic activity in alkaline media.
