Abstract

Pt/C has a good performance for decarboxylation of oleic acid, but its catalytic stability needs further improvement. In this work, metal oxide films with controllable thicknesses were synthesized using atomic layer deposition to protect the Pt in the Pt/C to increase its catalytic stability. Compared to Pt/C, which showed only a 17% yield of heptadecane at the fourth catalytic cycle, the Pt/C deposited with porous Al₂O₃ films after high-temperature calcination showed improved catalytic stability that still obtained a 41% yield of heptadecane at the fourth catalytic cycle. These findings are important for improving the stability of noble metal–based catalysts and reducing the cost of industrial biofuel production.
