Ru/rutile-TiO 2 catalysts with coverage-independent particle size and shape enable isolation of particle density effects in polyolefin hydrogenolysis
Nature · By Linxiao Chen ·
The 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.
