Scientific Achievement
Established mechanistic role of metal oxide support on the catalytic deconstruction of polyolefins under H2.
Significance and Impact
The lack of acidity and increased stability of Pt/SrTiO3 facilitates polymer deconstruction via hydrogenolysis, generating products that can be used directly as lubricants, whereas higher acidity and lower stability of Pt/SiO2-Al2O3 enables polymer deconstruction via competing hydrogenolysis and hydrocracking, generating mixtures of products that require further separation.
