Bibliometric Analysis on the Joint Application of Core-Shell Catalysts and Atomic Layer Deposition in Solide Oxide Fuel Cells

Abstract

This study presents a bibliometric analysis of the scientific output between 2010 and 2025 related to solid oxide fuel cells (SOFC), atomic layer deposition (ALD), and core-shell catalysts. Based on Scopus database records processed using the Bibliometrix R tool, various combinations of these themes were evaluated to map publications, authors, institutions, collaboration networks, geographic distribution, gaps, and emerging trends. The results indicate that the association between ALD and core-shell structures already constitutes a consolidated field, with the highest volume of publications. At the same time, approaches directly involving SOFCs remain in an emerging stage. Although no studies were found that integrate ALD, core-shell catalysts, and SOFC simultaneously, the qualitative indicators observed in the individual analyses suggest a significant gap and a promising, specialized research niche. The predominance of Asian and North American countries, such as China, South Korea, and the United States, was also observed, underscoring the strategic role of these nations in leading the development of advanced energy technologies. Overall, combining these approaches may drive significant advances in the development of more efficient and sustainable energy systems.
