“…The high reproducibility and stability of the electrodes fabricated by this technique have also been demonstrated [47,55]. Other advantages of magnetron sputtering are the high adhesion of films to the substrates, a high deposition rate that permits a short manufacturing time for the electrodes, and the possibility to sputter any metal, alloy, or other components varying the gas plasma composition [133]. An additional advantage in terms of costs is the possibility to fabricate electrodes, either anode or cathode, at room temperature, decreasing the fabrication cost and time [47].…”

Water electrolysis to obtain hydrogen in combination with intermittent renewable energy resources is an emerging sustainable alternative to fossil fuels. Among the available electrolyzer technologies, anion exchange membrane water electrolysis (AEMWE) has been paid much attention because of its advantageous behavior compared to other more traditional approaches such as solid oxide electrolyzer cells, and alkaline or proton exchange membrane water electrolyzers. Recently, very promising results have been obtained in the AEMWE technology. This review paper is focused on recent advances in membrane electrode assembly components, paying particular attention to the preparation methods for catalyst coated on gas diffusion layers, which has not been previously reported in the literature for this type of electrolyzers. The most successful methodologies utilized for the preparation of catalysts, including co-precipitation, electrodeposition, sol–gel, hydrothermal, chemical vapor deposition, atomic layer deposition, ion beam sputtering, and magnetron sputtering deposition techniques, have been detailed. Besides a description of these procedures, in this review, we also present a critical appraisal of the efficiency of the water electrolysis carried out with cells fitted with electrodes prepared with these procedures. Based on this analysis, a critical comparison of cell performance is carried out, and future prospects and expected developments of the AEMWE are discussed.

Aqueous zinc-ion batteries (ZIBs) with metallic Zn anodes have emerged as promising candidates for large-scale energy storage systems due to their inherent safety and competitive capacity. However, challenges of Zn anodes, including dendrite growth and side reactions, impede the commercialization of ZIBs. The regulation of the Zn/electrolyte interphase is a feasible method to achieve high-performance ZIBs with prolonged lifespan and high reversibility. Considering the as-made artificial interphase is the result of a combination of protection materials, protection mechanisms, and construction techniques, this review comprehensively summarizes the recent progress of interphase modulation and provides a systematic guideline for constructing ideal artificial layers. In addition to revealing the entanglement relationship between the failure behaviors of Zn anodes and timely concluding the emerging protection mechanisms for stable Zn/electrolyte interphase, this review also evaluates the constructing techniques in regard of commercialization, including engineering workflow, strength, shortcoming, applicable materials, and protection effect, aiming to pave the way to practical application. Finally, this review presents noteworthy points of ideal artificial layer. It is expected that this review can enlighten researchers to not only explore ideal interphases of Zn anodes for practical application, but also design other metal anodes in aqueous batteries with similar failure behaviors.

“…After that, These metal atoms are then deposited on the substrate material forming a metallic film. Magnetron sputtering increases the plasma density by introducing a magnetic field on the surface of the target cathode and utilizing the constraints of the magnetic field on the charged particles to increase the sputtering rate [34][35][36].…”

1-Phenylethanol (PHE) is a high-value chemical with various applications in fragrance and pharmaceutical industries. It is extensively used as strawberry fragrance additives in yogurts and chewing gums and an intermediate of anti-inflammatory drugs such as Ibuprofen. In this study, selective hydrogenation of acetophenone (AP) to PHE was investigated using platinum catalysts supported on different types of titanium dioxide including PC500 (pure anatase) and P25 (anatase mixed rutile). Pt was deposited on the titanium dioxide supports by pulsed direct current magnetron sputtering (PDC-MSD) method with deposition time spent on Pt coating at 3, 6, and 9 minutes. For comparison purposes, Pt/TiO2 catalysts were also prepared by incipient wetness impregnation method with similar Pt loadings (%). The characteristics and catalyst properties were analyzed by XRD, N2-physisorption, XPS, ICP-OES, TEM, CO-chemisorption, and H2-TPR. Hydrogenation of AP was carried out in a batch reactor at the pressure of 1 bar H2 and the temperature of 80oC for 2 hours using 2-propanol as the solvent. It was found that increasing sputtering time resulted in a larger average Pt particle size deposited on the TiO2 surface and increased amount of Pt loading (%). For any sputtering time used, platinum catalysts on PC500 TiO2 support provided higher selectivity of PHE than on P25 because of higher atomic ratio of Pt/Ti on the catalyst surfaces and higher Pt dispersion (%) on the PC500 TiO2 surface. However, increasing Pt loading (%) may also catalyze the hydrogenolysis of PHE to ethylbenzene (EB), resulting in lower PHE product. Moreover, at the reaction temperature of 80 oC could promote the hydrogenation of AP to PHE and inhibit hydrogenolysis of PHE to EB in 2-propanol solvent.
