“…[153][154][155] A recent work by Evan Ma [156] has used MD simulations to discuss the role of SRO and geometrically unfavorable motifs (GUMs) in amorphous alloys correlating the GUMs with the liquid-like regions in the observed plasticity for the alloys and highlighting the SRO as partially responsible for the thermodynamic and kinetic stability of the amorphous alloy. This point was recently confirmed for bimetallic alloys [132] and to track this surface and bulk transition in MGNs by means of computing chemistry (either by Stochastic methods or tracking trajectories via MD) would provide a unique perspective on the design of MGNs electrocatalysts. In fact the majority of MD studies on MGs have been focused on addressing structural issues either on thin-film [157] or bulk MGs [154] and there is literature deficit on computing chemistry applied to MGs or MGNs.…”

“…All three aforementioned authors have reported higher specific activity for ORR than Pt/C. [132] Following this concept, activated or dealloyed quaternary MGs would possess a wide distribution of different catalytic sites with several at close to optimal ORR activity in a Sabatier diagram that dominates the kinetics. Nesselberger et al attributed this improvement due to lattice-strain effect that arises from the dealloying of bi-metallic materials, [129] as previously demonstrated by Nørskov and co-workers [130] and Strasser et al [131] Kolla and Smirnova elaborate that the measured improvements are proportional to the fcc lattice parameter which is consistent with previous studies.…”

“…Depending on the activation method, a porous surface can also be created. [132] [135,136] Dealloying, either induced electrochemically or by chemical treatments, besides phase transformation, can also create a high surface energy which has a distinct deactivation dynamic.…”

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.

the bottleneck for the energy efficiency of fuel cells, metal-air batteries, and water splitting. [9][10][11] Developing active electrocatalysts is vital to achieve accelerated electrochemical reaction kinetics and to eventually obtain highly efficient electrochemical devices. Currently, precious metal-based materials, such as Pt, IrO 2 , and RuO 2 , are dominant among the catalysts for oxygen electrocatalysis because of their superior activity; although their large scale application is severely limited by their high cost and scarcity. [12][13][14][15][16][17] Therefore, this necessitates the design and development of earth-abundant, stable, yet highly active electrocatalysts toward practical energy storage and conversion devices.Transition metal oxides and their derivatives have been considered as promising electrocatalysts for the OER and ORR due to their earth-abundance and low cost, as well as intrinsic stability during the catalytic process. [9,[18][19][20][21][22][23][24] Among the various metal oxides, lithium metal oxides with the formula LiMO 2 (where M is a transition metal), which have been widely applied as cathodes for lithium ion batteries, constitute a new class of electrocatalysts. It has been reported that superior catalytic activity could be achieved by pinning the transition metal redox energies at the top of the O-2p band. [25][26][27][28] LiCoO 2 has recently been intensively explored as OER and ORR catalyst. [27,[29][30][31][32][33][34][35] However, its catalytic activity still needs to be enhanced to meet the requirements of practical applications. Toward the intelligent design of high performance electrocatalysts, two general strategies (enhancing the intrinsic activity and increasing the number of active sites) have been applied to improve the activity of targeted electrocatalysts. [36] Creating defects, modulating the electronic structure, and tuning the lattice strain are significant strategies to enhance the intrinsic activity of catalysts. [2,8] Nanostructure engineering by reducing the material's dimension and size is the most commonly deployed approach to increase the exposure of active sites. In particular, 2D materials possess exotic electronic properties and high surface atom ratio, which are significant for electrochemical reaction kinetics. [37,38] Hence, engineering 2D-based nanostructures is attracting ever-increasing attention toward catalysis and energy storage applications. [39][40][41][42][43] Moreover, the electronic conductivity of the catalyst system is also a vital factor for fast Developing low-cost and efficient electrocatalysts for the oxygen evolution reaction and oxygen reduction reaction is of critical significance to the practical application of some emerging energy storage and conversion devices (e.g., metal-air batteries, water electrolyzers, and fuel cells). Lithium cobalt oxide is a promising nonprecious metal-based electrocatalyst for oxygen electrocatalysis; its activity, however, is still far from the requirements of practical applications. Here, a new L...
