“…The electrophoresis deposition (EPD) is a versatile technique to fabricate thin and thick coatings on electrically conductive substrates 27 . Most of the nano-objects have surface charges when they are dispersed in a solution, this surface charge can provide a highly dispersed solution 28 . When apply an electric field to the solution, these charged units in aqueous or non-aqueous suspension can move onto a shaped electrode of opposite charge under the role of applied electric field 29 .…”

We successfully developed a simple electrophoretic deposition (EPD) method to decorate the MoSe2 nanosheets on the carbon fiber surface of carbon cloth (MoSe2/CC). With this process, MoSe2 nanosheets can be uniformly and tightly deposited on this flexible conductor to form a 3D binder-free electrode for hydrogen evolution reaction (HER). The film thickness can also be controlled by the EPD time. Directly used as binder-free electrodes for hydrogen evolution reaction, the as-prepared 3D MoSe2/CC samples exhibit excellent catalytic activity in an acidic electrolyte (21 mA/cm2 at an over-potential of 250 mV). Variation of MoSe2 nanosheets film thickness in the electrodes could affect the catalytic activity, and it was found that the MoSe2/CC sample prepared with 60 min EPD time shows the highest HER activity amongst these different thickness samples. Moreover, stability tests though long-term potential cycles (no degradation after 1000 continuous potential cycles) and extended electrolysis confirm the exceptional durability of the catalyst. This development offers us an attractive and active 3D electrode for electrochemical water splitting.

“…A comparison of the PTFE and Nafion solution in the catalyst layer of the electrodes fabricated by EPD revealed PTEF to have better performance and be more suitable for use at high temperatures (160 • C). A nano-architectured Pt catalyst layer was prepared by the pulsed electrophoretic deposition (PED) [317][318][319]. Yu et al synthesized branched Pt nanoparticles on a carbon black electrode by PED [317].…”

“…PED was carried out in a suspension at various pH containing Pt nanoparticles colloid at a duty cycle {t on /(t on + t off )} of 25% and a t cycle (t on + t off ) time fixed to 1 s. The Pt-carbon black electrode showed higher mass activity and specific activity for the methanol oxidation reaction than a commercial Pt/C catalyst. Recently, Adibish et al employed PED to synthesize Pt/C catalyst electrodes at different deposition times and duty cycles [318]. The electrochemical active surface area (ECSA) of the Pt/C electrode synthesized by PED showed the highest value when the deposition time was 10 min and the duty cycle {t on /(t on + t off )} was 25%.…”

A Comprehensive Review of Nanomaterials Developed Using Electrophoresis Process for High-Efficiency Energy Conversion and Storage Systems

Research carried out over the last few decades has shown that nanomaterials for energy storage and conversion require higher performance and greater stability. The nanomaterials synthesized by diverse techniques, such as sol-gel, hydrothermal, microwave, and co-precipitation methods, have brought energy storage and conversion systems to the center stage of practical application but they still cannot meet the capacity and mass production demands. Most reviews in the literature discuss in detail the issues related to nanomaterials with a range of structures synthesized using the above methods to enhance the performance. On the other hand, there have been few critical examinations of use of the electrophoresis process for the synthesis of nanomaterials for energy storage and conversion. The nanomaterials synthesized by electrophoresis processes related to colloidal interface science in the literature are compared according to the conditions to identify promising materials that are being or could be developed to satisfy the capacity and mass production demands. Therefore, a literature survey is of the use of electrophoresis deposition processes to synthesize nanomaterials for energy storage and conversion and the correlations of the electrophoresis conditions and properties of the resulting nanomaterials from a practical point of view.
