Cerium (Ce) — 10-Year Trends

As of 2026-09-25 · the last 10 years

Cerium’s research intensity stands at about 98% of its own all-time peak, a level reached within this window in 2024.

Research intensity ran from about 75% of the element's own all-time peak in 2016 to about 98% in 2026 — a steady climb, and the all-time peak (2024) 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 material research community is Ceria Catalysts for Gas Shift and Soot Oxidation, where cerium oxide serves as a catalyst for water-gas shift reactions and soot combustion, leveraging its oxygen vacancy dynamics to enhance catalytic activity. In this context, cerium is a minor presence in a much larger community, with about 9% of its papers involving cerium. This group accounts for about 23.5% of cerium's recent research, a steady share compared to the previous period. The community’s foundational work includes a 2016 review on the fundamentals and catalytic applications of CeO2-based materials, cited over 2,700 times, and recent high-impact studies on oxygen vacancies in ceria, cited over 130 times.

A second major area is Cerium Nanoparticle Synthesis and Antioxidant Applications, focusing on the green synthesis of cerium dioxide nanoparticles and their antioxidant and antibacterial properties in treating cancer and oxidative stress. Here, cerium is one strand of a broader community, with about 27% of its papers involving cerium. This community represents about 11.9% of the element's recent research, holding steady from the prior period. Key work includes a 2025 study on a dynamically phase-adaptive regulating hydrogel for wound healing, cited over 120 times, and a 2024 paper on multifunctional hydrogels for diabetic wound healing, cited over 180 times.

The third material community is Cerium Oxide Heterojunctions for Photocatalytic Degradation, where cerium oxide forms heterojunctions with carbon nitride and metal-organic frameworks to degrade pollutants and reduce CO2 under visible light. Cerium is a minor presence in this much larger community, with about 2% of its papers involving cerium. It accounts for about 6.2% of the element's recent research, a steady share. Notable recent work includes a 2025 paper on integrating S-scheme photocatalysis with tandem carbonylation, cited over 110 times, and a 2023 study on photocatalytic degradation of methylene blue dye, cited over 300 times.

Across these communities, the composition of cerium's research has remained largely stable, with the "Other research communities" band rising to hold about 58.4% of the element's recent work. For a deeper look at the element's current standing, see the Last 12 Months and Executive Brief reports.
