All the materials were characterized for chemical, textural and structural properties using a range of analytical techniques. The M/NT-Ti (M: Pd, Pt, or Au) catalysts exhibit low nanoparticle sizes (1.8 <NPs[removed] Pt ≈ Au > support > non-catalyst. The Py-GC/MS suggest that the catalysts participate in the secondary reactions of dealkylation, dehydrogenation, isomerization, aromatization, and cyclization leading to a higher formation of BTX than the uncatalyzed reaction. Finally, a comprehensive reaction pathway describing the catalytic pyrolysis of WT over Pd/NT-Ti was proposed by studying the catalytic pyrolysis of individual polymers constituting the waste tires, and D,L-Limonene. © 2021 Elsevier B.V.enBTXCatalytic pyrolysisNoble metalTitanate nanotubesWaste tiresArtículoCC BY-NC-ND 4.0 CÓDIGO LEGAL Atribución-NoComercial-SinDerivadas 4.0 Internacional10.1016/j.cattod.2021.06.029
