“…Ti is selected as the additional alloy element to adjust the electronic structure to tailor the hydrogen evolution, − because it can form solid solutions with Ni and Co, hence avoiding the formation of additional non-active phases. The compositional library is synthesized by magnetron co-sputtering deposition, ,,− where we use pure metals in the three sputtering targets (Figure a). The composition gradient within the sputtered alloy library is controlled by the tilt angle of the target elements (see, e.g., ref ).…”

Multicomponent alloys are promising candidates as catalysts for hydrogen evolution reaction (HER) in aqueous solutions owing to the synergic effects between elements. However, due to the vast compositional space they occupy, identifying the optimum catalyst is challenging both computationally and experimentally. In this paper, we propose a scalable highthroughput bubble screening method that is able to identify the multicomponent alloys with the highest catalytic properties. As a demonstration, the optimum compositions with advanced intrinsic catalytic activities in the ternary Ni−Co−Ti and Ni−Fe−Au alloys are identified using this method. The advanced catalytic performance of the optimum Ni 56.5 Co 35 Ti 8.5 alloy ribbon is further confirmed by the individual electrochemical tests, with an over-potential of about 425 mV at 500 mA cm −2 and a Tafel slope of about 82 mV dec −1 . This is attributed to the low atomic packing density and low electron binding energy. The introduced scalable high-throughput strategy is not limited to ternary catalysts for HER but is also expected to be equally useful for exploring catalysts in higher composition alloy systems and even for oxygen evolution reactions.

“…Optical detection methods have the advantages of fast speed and simple operation and are suitable for the in situ study of metal corrosion, especially when combined with computer image processing technology. In this method, the samples are immersed in a corrosive medium, and optical techniques such as digital imaging, [59] digital holography, [60,61] optical profilometry, [62] and optical screening [63] are used to characterize the corrosion process in situ or offline.

High‐throughput experimental techniques can accelerate and economize corrosion evaluation, and thus, have great potential in the development of new materials for corrosion protection such as corrosion‐resistant metals, corrosion inhibitors, and anticorrosion coatings. This concise review highlights high‐throughput experimental techniques that have been recently applied for corrosion research, including (i) the high‐throughput preparation of metal samples in the form of thin films or bulk materials, (ii) high‐throughput experiments based on corrosive solutions with independent or gradient parameters, (iii) high‐throughput evaluation of changes in physicochemical properties, and (iv) high‐throughput corrosion evaluation by electrochemical methods. To advance automated and intelligent corrosion research, future directions for the development of the high‐throughput corrosion experimental and characterization techniques are also discussed.

An automated platform that can perform standard electrochemical tests at the micro-scale will greatly facilitate the electrochemical property screening of a combinatorial materials chip. Here we report an automated test platform for high-throughput characterization of metallic materials’ local electrochemical properties. It integrates four components, including a micro-electrochemical cell, an automatic liquid refresh system, a programmed scanning automated XYZ stage, and a control system. The high-throughput test cell array is constructed using capillary and lithography techniques. The automation is achieved by a Lab View program that can control all the components. We validated the system reliability by characterizing the surface electrochemical activity of the Fe-based alloy in a Fe–Cr–Ni combinatorial materials chip. Combining electron probe micro-analysis, X-ray diffraction, and the above local electrochemical tests, the relationship between composition, crystal structure, and the electrochemical properties of the Fe-based alloy has been established and discussed. The results demonstrate that this is a highly promising technique for high-efficiency data collection for database construction and corrosion-resistant material design.
