As of 2026-09-11 · the last 10 years
Research intensity has climbed steadily to reach 100% of the element's all-time peak, a high first achieved within this window.
Research intensity ran from about 80% of the element's own all-time peak in 2016 to about 100% in 2026 — a steady climb, and the all-time peak (2025) falls inside this window. Over the same span its share of research attention across all elements rose. Among the 118 elements, cerium has a larger-than-average research literature.
The number of papers involving the element rose from about 7,142 in 2016 to about 20,203 in 2025 (2.83x). That is faster than the literature as a whole grew over the same years, so the element gained ground in the wider body of research.
The largest body of work belongs to Cerium-Based Catalysts for Oxidation, Reduction, and Environmental Remediation. In this community, cerium is central, appearing in about 32% of its papers. The research focuses on cerium dioxide, CeO2 catalysts, and ceria nanoparticles, with distinctive work on synthesis and environmental applications. While this group accounts for about 39% of cerium's recent research, its share has declined from 45% in the previous period. The field’s foundation is anchored by a 2016 review on the fundamentals and catalytic applications of CeO2-based materials, cited over 2,700 times, and a 2019 study on selective catalytic reduction of NOx, cited over 1,700 times. Recent high-impact work includes a 2025 paper on oxygen vacancies in ceria, cited over 130 times, and a 2025 study on nanoscale grain boundaries boosting ceria surface oxygen reactivity, also cited over 130 times.
A second significant area is Cerium Oxide Redox Catalysis for Solar Thermochemistry. Here, cerium acts as a redox oxygen carrier in solar thermochemical cycles and low-temperature CO2 reduction. Cerium is a minor presence in this broader community, involved in about 6% of its papers. Its share of cerium’s research has remained steady at about 5%. Key work includes a 2018 paper on low-temperature CO2 methanation over CeO2-supported Ru, cited over 1,000 times, and a 2024 study on facilitating the dry reforming of methane with interfacial synergistic catalysis, cited over 190 times.
A third distinct area involves Gadolinium-Doped Ceria Electrolytes for Low-Temperature Fuel Cells. These papers focus on gadolinium-doped ceria as a solid electrolyte, optimizing ionic conductivity for intermediate-temperature solid oxide fuel cells. Cerium is one strand of this broader community, appearing in about 10% of its papers. Its share of cerium’s research has remained steady at about 5%. Notable recent work includes a 2025 paper probing dopant size effects on defect clustering in lanthanide-doped ceria, cited about 28 times, and a 2024 study on synergistic proton and oxygen ion transport in fluorite oxide-ion conductors, cited about 59 times.
Overall, the composition of cerium research is shifting. The dominant catalyst community is losing share, while the remainder of the field—comprising various smaller communities—is gaining ground, rising from 43% to 51% of the element's recent research.
