“…[83] By using an acid treatment composed of 1 m HF done over a PdZr MG, the authors reported a much higher reaction rate than the original melt-spun state. For example, chemical methods have been reported with HNO 3 , [81,84] KOH, [87] and H 2 SO 4 [88] for Fe-, Zr-, and Ni-based MG alloys.

transformers [2] and load bearing applications. [3] In the last few decades, the study of nanomaterials has become a central focus in nanoscience and nanotechnology. [4] In fact, many studies have shown that with reduction in size, nanomaterials display novel electrical, mechanical, chemical and optical properties, which are largely believed to be the result of surface and quantum confinement effects. [4,5] Remarkably, this trend has found traction in the metallic glass field where metallic glasses nanostructures (MGNs) demonstrate an important role in many applications such as light harvesting, [6] photovoltaic, [7] biomedical, [8] magneto-optical, [9] organic synthesis, [10] lithium-ion batteries [11] and electrocatalysis. [12] Recently, MGNs are receiving increased attention due to their distinguished performance, such as high activity and long term stability in electrocatalytic reactions. [12,13] Although several review papers have already covered the topic of nanopatterning of bulk metallic glasses (BMGs), [14][15][16] the correlation between recent synthetic methods and electrocatalytic applications for MGNs has not been thoroughly addressed. Moreover, there is currently no review that unites MGNs synthesized from different approaches (top-down and bottom-up) with conventional electrochemical reactions. Therefore, in this review our mission is to: 1) present a focused perspective on the latest fabrication techniques of MGNs toward the pursuit of novel electrocatalysts and electrodes; 2) highlight recent advances in computational screening and predictions that could be applied toward new metallic glass electrocatalyst discovery; and 3) report distinct advancements in electrocatalytic applications related to MGNs by creating a comprehensive discussion for commonly employed kinetic parameters and their connection with the unique material structure. Finally, as the first progress report on the metallic glass based electrocatalysts, we will also highlight some of the challenges that need to be addressed toward future progress in this field.BMGs are those metallic glasses (MGs) that can be made in 'bulk' scale with good glass forming abilities, [17] representing a versatile platform for many applications. To date, a wide range of BMG-forming alloys have been developed, including Zr-, [18] Fe-, [19] Cu-, [20] Ni-, [21] Ti-, [22] Mg-, [23] Pd-, [24] Au-, [25] and Pt-based compositions. [26] Moreover, the increased disorder brought by the higher degree of multinary systems is believed to contribute to improving the glass formation. [27] The evolution to multicomponent alloys of the most recent MG studies has also made them natural candidates for catalysis. The amorphous multinary Recent advances in metallic glass nanostructures (MGNs) are reported, covering a wide array of synthesis strategies, computational discovery, and design solutions that provide insight into distinct electrocatalytic applications. A brief introduction to the development and unique features of MGNs with an overview of top-down and bottom-up sy...

“…The catalytic studies [128] on the hydrogenation of carbon monoxide by Fe-based alloy indicated that the activity is augmented by a treatment in HNO 3 solution. Guczi et al [129] thought that the surface composition and valence state determined in depth were related to the catalytic activity and selectivity revealed in CO + H 2 reaction. An increased number of nickel and iron sites by removing of the prevailing boron oxide, iron oxide, and iron oxide layer after HCl treatment was responsible for the enhanced catalytic activity, as shown in Figure 15, that is, the activity of the FeB sample in as-received state was about twice that observed for the FeNiB sample, on the other hand, comparing the HCl etched samples, the activity of the FeNiB alloy was about 30 times higher than that of the FeB ribbon.…”

Metallic glasses exhibit excellent corrosion resistance and electrocatalytic properties, and present extensive potential applications as anticorrosion, antiwearing, and catalysis materials in many industries. The effects of minor alloying element, microstructure, and service environment on the corrosion resistance, pitting corrosion, and electrocatalytic efficiency of metallic glasses are reviewed. Some scarcities in corrosion behaviors, pitting mechanism, and eletrocatalytic reactive activity for hydrogen are discussed. It is hoped that the overview is beneficial for some researcher paying attention to metallic glasses.

“…Since the first report of Fe-based metallic glass as a catalytic material in 1981 [1], a number of investigations have been focused on the synthesis of Fe-based metallic glasses for catalytic applications, such as ammonia synthesis [2], acetylene hydrogenation [3], CO hydrogenation [4][5][6] and hydrogenation [7]. On the other hand, the metallic glasses also showed good electrocatalytic activities, and the activities were further improved by the pretreatment in an acid solution such as HF, HCl or HNO 3 [8][9][10]. The improved electrocatalytic properties were attributed to changes in the surface compositions and/or surface area by the pretreatment.…”

The electrocatalytic activity of newly developed Fe-based bulk metallic glasses was evaluated by polarization and impedance measurements in deaerated 1 M KOH solution at room temperature. The electrocatalytic activity as well as the glass-forming ability of the Fe 73 C 3 Si 7.3 B 8.5 P 5.7 Mo 2.5 alloy was improved by the partial substitution of Fe with 13.5 at% Co. In hydrogen evolution reaction, the metallic glasses exhibited higher activity than the activity of G14 (Fe 60 B 10 Si 10 Co 20 ) metallic glass, which has been reported to be comparable to the activity of Pt electrode. The activity was further improved after a chemical pretreatment in 1 M HF solution for 1 min due to the formation of cobalt-rich layer with a large effective surface area.
