“…The capacity fading after the initial cycling is attributed to volumetric changes that are most severe when the electrodes are fully lithiated, which can lead to a break-up of the surrounding Li/alloy matrix, electronic isolation of the particles, and the consequent trapping of lithium in heavily lithiated Li x Ag particles [21]. The similar behavior was also observed in other Ag and Co based alloy anodes [5,[21][22][23]. In overall, the porous Ag-Co-Ni electrodes with 10 wt.% of Ag seem to be a good candidate and an interesting for high power lithium-ion batteries.…”

“…Choosing an electrode material for commercial applications depends upon the electrocatalytic activity and cost. In this regard, Co-Ni, as reported to be highly corrosion resistant with interesting results when doped with transition metals, has been chosen as an effective electrocatalytic electrode [5]. One or more species should be introduced to overcome such shortcoming and at the same time still keep excellent electrochemical performances.…”

and industrial interests in energy conversion processes, such as electrocatalytic and thermocatalytic reactions, the availability of suitable catalysts for target reactions with superior sustainability, selectivity, reactivity, and endurability is the key. [6] Recent studies have suggested that catalysts alloying with RE elements significantly influence their performance in energy conversion and storage. [7] The RE elements with unique electronic configurations of [Xe] 4f n−1 5d 0−1 6s 2 (n = 1-15) give an extra rhythm in tuning their functional properties from the perspective of their electronic and catalytic activities and are significantly promising in increasing the materials' activity and performance stability for a particular system of interest. [8] RE-based alloy catalysts have been ameliorating capabilities from both the RE elements and their alloys, which could pave the way for the industrialization of these alloy catalysts in the near future.Alloying with RE elements gives the alloy richer mechanistic functionalities, electronic structures, activities and spatial arrangements, resulting in well-controlled surface reaction kinetics and better reaction activities. [9] For instance, RE alloys have more stable structures than common transition-metalbased alloy catalyst due to the exceptionally negative alloy formation energies; Pt-RE alloys exhibit the highest activity of all ORR catalysts ever reported; and some RE alloys have low work function due to the anionic electrons contained in the unit cell etc. [7] Chemical synthesis of RE alloys for catalytic To improve the performance of metallic catalysts, alloying provides an efficient methodology to design state-of-the-art materials. As emerging functional materials, rare-earth metal compounds can integrate the unique orbital structure and catalytic behavior of rare earth elements into metallic materials. Such rare-earth containing alloy catalysts proffer an opportunity to tailor electronic properties, tune charged carrier transport, and synergize surface reactivity, which are expected to significantly improve the performance and stability of catalysis. Despite its significance, there are only few reviews on rare earth containing alloys or related topics. This review summarizes the composition, synthesis, and applications of rare earth containing alloys in the field of catalysis. Subsequent to comprehensively summarizing and constructively discussing the existing work, the challenges and possibilities of future research on rare-earth metal compound materials are evaluated.
