“…Tan et al [290] proposed the application of N-doped G 30 with tunable porosity for REEs separation. The pores with controlled diameters (from few to several tens of nanometers) and pyrrolic N determined membrane properties, especially high selectivity during Sc 3+ separation from other REEs (Fig.…”

“…Other critical applications of rare earths [15], which are considered as "the secret ingredients of modern industry" [16] were identified in the sectors and devices strictly associated with human life, e.g. magnets [17,18], catalysts [19][20][21][22], inorganic materials including ceramics [23][24][25][26][27], petrochemicals [28,29], electronics [30,31], battery alloys [32][33][34][35][36][37] and additives/enhancers for more advanced materials [38,39]. Paradoxically, industrial separation for REEs from mineral ores seemed less clean than their by-end uses [40].…”

“…[67] Recently, a study by Xia et al (2022) was published presenting a sustainable recycling route for neodymium (Nd) contained in dielectric waste. [68] Within this process, concentrated HNO 3 was used as a leaching agent, and Nd could be recovered in large amounts by oxalate precipitation. Recycling of ceramic SOC components will possibly be guided by these initial approaches or by similar recovery routes, such as the handling of battery cathode materials or other electronic waste (e-waste) materials.…”

more than 70% of the global energy demand in the power generation, transport, and industrial heating sectors is covered by fossil fuels. [1] However, greenhouse gas (GHG) emissions are essentially associated with two major drawbacks: the scarcity of fossil fuel resources and the evidenced change in climate patterns. [2] In order to mitigate further GHG emissions, the European Union (EU) has committed itself to become CO 2neutral by 2050. [3] To achieve the envisaged energy transition from fossil fuels to renewable energy sources, efficient energy storage systems, are required. For longterm and high-volume storage, hydrogen as a chemical energy carrier seems to be the most reliable choice in this context. The upcoming expansion of hydrogen technologies is a key aspect of the implementation of climate protection policy, as demonstrated by several studies. [4] On an international scale, more than 30 countries have already launched their hydrogen strategies and roadmaps. [5] To produce hydrogen at scale electrolysis is seen as the most advanced technology. Currently, there are four major water electrolysis applications for generating green hydrogen, including proton exchange membranes (PEMs), alkaline water electrolysis (AWEs), alkaline anion exchange membranes (AEMs), and solid oxide cells (SOCs). [6] While PEMs, AWEs, and AEMs are known for their low operating temperatures (20-200 °C), SOCs are classified as high-temperature applications (500-1000 °C) that offer certain benefits. When the utilization of heat is taken into account, the energy efficiency of SOCs can reach more than 90%. [7] In addition, the operating mode can be either set to fuel cell (SOFC) or electrolysis cell (SOEC) in one unit. These are described as reversible SOCs (rSOCs). This special feature therefore makes SOCs easy to adapt to energy surpluses or deficiencies, depending on environment (e.g., whether the wind is blowing or the sun is shining; day/night) and on demand. The research on new SOC materials might also enable long-term operation at lower temperatures (≈ 500 °C), [8] as well as the co-electrolysis of H 2 O and CO 2 for syngas production, or even pure CO 2 -electrolysis on an industrial scale. [9] However, regardless of the type of electrolyzer being used, lifetime is limited. SOC aging processes such as voltage degradation, interdiffusion, foreign phase formation, oxidation or fracturing can result in reduced cell performance and in some instances lead to the complete failure of the system. [10,11] Until lately, SOC recycling-related topics have attracted little attention. As part of the EU-funded project HYTECHCYCLING (finished in 2019), initial proposals for recycling various hydrogen Alongside the generation of renewable power and its storage in batteries, hydrogen technologies are essential to enable a deep decarbonization of the energy system. These technologies include solid oxide cells (SOCs), which can be operated as electrolyzers to generate hydrogen or syngas and/or for power supply in fuel cell mode and demonstrate th...

“…Indeed, lots of work has been done in the past few years focusing on the recovery of the elements commonly found in magnets, e.g. Neodymium-Iron-Boron magnets (NdFeB) [5][6][7][8][9][10][11][12] or electronic components that can be enriched in REEs, such as Nd-based capacitors [13].…”
