Kind: research · Impact: medium

## In brief

- Researchers synthesized Ru/rutile-TiO2 catalysts whose particle size and shape stay constant while particle density varies.
- This design isolates the effect of particle density, which is normally hard to separate from other factors in catalysis.
- The work applies these catalysts to polyolefin hydrogenolysis and was published in Nature Catalysis on 9 November 2026.

## Why it matters

Particle density effects are difficult to disentangle from other variables, so a catalyst series with fixed size and shape gives researchers a cleaner way to study how density affects polyolefin hydrogenolysis.
