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.

Pt / C具有良好的油酸脱羧性能，但其催化稳定性有待进一步提高。在这项工作中，使用原子层沉积法合成了厚度可控的金属氧化物膜，以保护Pt / C中的Pt以增加其催化稳定性。与在第四次催化循环中仅显示17％的庚烷收率的Pt / C相比，在高温煅烧后沉积有多孔Al ₂ O ₃膜的Pt / C表现出改善的催化稳定性，仍然获得41％的收率。在第四个催化循环中的庚烷。这些发现对于提高贵金属基催化剂的稳定性并降低工业生物燃料生产成本非常重要。
