Special Issue Information

Dear Colleagues,

The global pursuit of sustainable energy solutions has intensified research efforts in electrocatalysis and advanced battery technologies—two cornerstones of modern energy conversion and storage systems. Electrocatalysis plays a pivotal role in processes like water splitting for green hydrogen production and oxygen reduction in fuel cells, while batteries address the growing demand for grid-scale energy storage and portable electronics. Nanomaterials, with their unique high surface area, tunable electronic structures, and enhanced mass transport properties, have emerged as game-changers in overcoming the performance limitations of traditional catalysts and battery materials. This Special Issue aims to showcase cutting-edge research that leverages nanoscale engineering to push the boundaries of both fields. It seeks to bring together original articles, reviews, and perspectives from interdisciplinary teams, fostering knowledge exchange and accelerating the translation of fundamental discoveries into practical energy technologies.

The scope of this Special Issue encompasses a broad range of topics across electrocatalysis and batteries. In electrocatalysis, contributions may focus on the design and synthesis of nanostructured catalysts for key reactions (HER, OER, ORR, CO₂RR), emphasizing structure–activity relationships, mechanism elucidation, and stability enhancement via strategies like heterostructure construction, defect engineering, and doping. For batteries, submissions could explore nanomaterial applications in electrode materials (e.g., high-capacity anode composites, sulfur cathodes with polysulfide trapping) and electrolyte components (e.g., nanoscale solid electrolytes, ion-conducting additives), alongside advanced characterization techniques to decode ion transport and interfacial phenomena. By highlighting innovative nanomaterial designs, scalable fabrication methods, and real-world performance validation, this Special Issue will serve as a critical resource for researchers and industry professionals dedicated to advancing sustainable energy systems. We invite authors to share groundbreaking work that drives the development of high-efficiency, durable, and cost-effective energy technologies powered by nanomaterials. In this Special Issue, original research articles and reviews are welcome. Research areas may include (but are not limited to) the following:

  • Nanostructured catalysts for key electrocatalytic reactions (HER, OER, ORR, CO₂RR);
  • Structure–activity relationships and mechanism elucidation of nanocatalysts;
  • Stability enhancement of nanocatalysts via heterostructuring, defect engineering, or doping;
  • Nanomaterial applications in battery electrode materials (high-capacity anodes, sulfur cathodes);
  • Nanoscale electrolyte components for advanced batteries (solid electrolytes, ion-conducting additives);
  • Advanced characterization of ion transport and interfacial phenomena in nanomaterial-based batteries.

We look forward to receiving your valuable contributions.

With the growing global demand for sustainable resources, recycling spent lithium-ion batteries has become a strategic priority. Conventional pyrometallurgical and hydrometallurgical methods suffer from high energy consumption, severe pollution, and structural destruction, making them unsuitable for regenerating high-nickel cathodes. In this work, spent polycrystalline high-nickel LiNi0.9Mn0.1O2 cathodes were selected, and an upcycling strategy integrating acid etching, hydrothermal relithiation, short-time annealing, and simultaneous Li4Ti5O12 (LTO) coating was developed. This process directly transformed degraded polycrystalline cathodes into single-crystal cathode materials with excellent structural stability and electrochemical performance. During regeneration, lithium compensation and lattice recrystallization effectively repaired lithium loss, reduced Li/Ni cation mixing, reactivated the degraded structure, and reconstructed a highly ordered layered single-crystal framework. The LTO coating further stabilized the cathode/electrolyte interface, suppressed side reactions, alleviated volume strain, and promoted Li+ transport kinetics. Electrochemical measurements showed that the regenerated single-crystal cathode exhibited superior structural integrity, strong resistance to crack propagation, low polarization, excellent rate capability, and long-term cycling stability. A capacity retention of 84.3% was achieved after 300 cycles at 1C, outperforming commercial polycrystalline cathodes. This strategy provides an efficient and promising route for the direct regeneration of spent high-nickel ternary cathodes. Full article

The CNT-supported nanodispersed Pt–Mo catalysts for the ethanol electrooxidation reaction in the alkaline solution are synthesized and their characteristics are studied. Based on the XPS studies in a wide range of platinum content (10–40 wt %), it is found that in the composition of the catalysts, platinum is predominantly in the metallic state, and molybdenum is in the hexavalent form, probably in the form of MoO3 oxide. According to the XRD and electrochemical studies, the Pt/CNT and PtMo/CNT catalysts with equal platinum contents (~20 wt %) are characterized by similar platinum crystallite sizes (5–10 nm) and electrochemically accessible surface areas (23–26 m2/gPt). This indicates that platinum is not shielded by the molybdenum compounds. When the platinum content increases above 20 wt %, the Pt:Mo atomic ratio increases (the nominal ratio is 1:1), which may be due to the decoration of molybdenum oxide with platinum nanoparticles. A study of the kinetics of the ethanol electrooxidation reaction showed that the activity of the PtMo/CNT system is higher than that of the Pt/CNT catalyst. However, the efficiency of platinum use decreases as its content in the PtMo/CNT system increases from 10 to 40 wt %. On the other hand, the systems containing 20–40 wt % Pt exhibit the highest activity per unit catalyst weight, making them very promising for use as a component of the anode active layer of a fuel cell. The tests of the alkaline ethanol fuel cell based on the synthesized catalysts show the maximum power density of 29 mW/cm2, which corresponds to the level of the best literature parameters under similar experimental conditions.

Water electrolysis using electricity generated from renewable sources is a promising approach for producing green hydrogen. However, this process requires the development of electrocatalysts that are not only highly active and durable but also low-cost. Considerable efforts are being directed toward discovering and optimizing such materials, and this study contributes to the ongoing research in this area. In this work, three novel LaMnO3 perovskite–graphene oxide hybrids—namely LaMnO3/GO, Ag-doped LaMnO3/GO, and Pd-doped LaMnO3/GO—were synthesized and investigated for their electrocatalytic activity in water electrolysis under strongly alkaline conditions. To the best of our knowledge, these hybrid materials have not been previously reported in the context of electrocatalytic water splitting. Among the electrodes fabricated and tested for the hydrogen evolution reaction (HER), the one based on a catalyst ink containing Pd-doped LaMnO3/GO mixed with carbon black showed the best performance, achieving a low overpotential of 0.385 V at a current density of −10 mA/cm2. It also demonstrated good stability in the alkaline electrolyte and exhibited a Tafel slope of 0.34 V. These findings highlight the potential of the studied materials as effective and previously unreported electrocatalysts for water splitting. Full article
