Liu B, Westman Z, Richardson K, Lim D, Stottlemyer A, Gillis P, et al.
ACS Macro Lett . 2024 Mar; 13(4):435-439. PMID: 38546447
Polyurethane (PU) is the sixth most used plastic in the world. Because many PU derived materials are thermosets and the monomers are valuable, chemical recycling to recover the polyol component...

Liu B, Westman Z, Richardson K, Lim D, Stottlemyer A, Farmer T, et al.
ACS Sustain Chem Eng . 2024 Mar; 12(11):4435-4443. PMID: 38516400
Chemical recycling of polyurethane (PU) waste is essential to displace the need for virgin polyol production and enable sustainable PU production. Currently, less than 20% of PU waste is downcycled...

Robatjazi H, Battsengel T, Finzel J, Tieu P, Xu M, Hoffman A, et al.
ACS Nano . 2024 Feb; 18(8):6638-6649. PMID: 38350032
Strong metal-support interactions (SMSIs) are well-known in the field of heterogeneous catalysis to induce the encapsulation of platinum (Pt) group metals by oxide supports through high temperature H reduction. However,...

Zang W, Lee J, Tieu P, Yan X, Graham G, Tran I, et al.
Nat Commun . 2024 Feb; 15(1):998. PMID: 38307931
Single-atom catalysts (SACs) offer efficient metal utilization and distinct reactivity compared to supported metal nanoparticles. Structure-function relationships for SACs often assume that active sites have uniform coordination environments at particular...

Lee J, Tieu P, Finzel J, Zang W, Yan X, Graham G, et al.
JACS Au . 2023 Sep; 3(8):2299-2313. PMID: 37654595
The addition of platinum-group metals (PGMs, e.g., Pt) to CeO is used in heterogeneous catalysis to promote the rate of redox surface reactions. Well-defined model system studies have shown that...

Ro I, Qi J, Lee S, Xu M, Yan X, Xie Z, et al.
Nature . 2022 Sep; 609(7926):287-292. PMID: 36071187
Metal-catalysed reactions are often hypothesized to proceed on bifunctional active sites, whereby colocalized reactive species facilitate distinct elementary steps in a catalytic cycle. Bifunctional active sites have been established on...
