Palladium (Pd) — 10-Year Trends

As of 2026-09-25 · the last 10 years

Palladium’s research intensity has settled at about 72% of its own all-time peak, a level reached after a steady decline from a high point that occurred just before this window began.

Research intensity ran from about 99% of the element's own all-time peak in 2016 to about 72% in 2026 — a steady decline, and the all-time peak (2015) lies before this window. Over the same span its share of research attention across all elements fell. Among the 118 elements, palladium has a larger-than-average research literature.

The number of papers involving the element rose from about 11,507 in 2016 to about 19,366 in 2025 (1.68x). That is slower than the literature as a whole grew over the same years, so the element lost ground in the wider body of research even as its own count rose.

The core of palladium’s recent literature is defined by its role in organic synthesis, specifically Palladium in Asymmetric and Cross-Coupling Reactions. This community focuses on palladium-catalyzed Suzuki and Miyaura couplings, as well as asymmetric transformations using aryl halides, with distinctive work on palladium nanoparticles and complexes. While palladium is one strand of a broader community—about 20% of its papers involve palladium—it remains the largest single area of focus for the element, accounting for about 47.5% of palladium’s recent research. However, this share has declined from 55.7% in the previous period. The community’s weight is carried by recent high-impact work, such as a 2023 Nature paper on autonomous chemical research with large language models, cited over 930 times, alongside foundational reviews like a 2016 Chemical Reviews article on C–N cross-coupling, cited over 2,900 times.

A second significant area is Palladium Catalysis for Alcohol Oxidation and Hydrogen Synthesis, where palladium nanoparticles and nanocrystals catalyze the oxidation of formic, methanol, and ethanol to generate hydrogen. Here, palladium is a minor presence in a much larger community—about 4% of its papers involve palladium—and it holds about 5.4% of the element’s recent research, a share that has remained steady. This field is anchored by highly cited work such as a 2016 Chemical Reviews review on electrocatalysts for oxygen reduction, cited over 3,900 times, and a 2016 Science paper on photochemical synthesis of atomically dispersed palladium catalysts, cited over 2,000 times.

Finally, Palladium Catalysts for Methane Oxidation and Hydrogenation involves supported palladium nanoparticles driving methane combustion, selective oxidation, and hydrogenation. Palladium is a minor presence in this community—about 3% of its papers involve palladium—and it accounts for about 4.3% of the element’s recent research, also steady. Notable work here includes a 2023 Science paper on cerium dioxide support nanocrystals dictating reactivity of highly dispersed palladium catalysts, cited over 330 times.

As a whole, the composition of palladium research has shifted away from its traditional stronghold in cross-coupling reactions, which lost share, while the remainder of the field—comprising other smaller communities—has risen to hold about 42.8% of the element’s recent research.
