Developing sulfur-tolerant catalysts for industrial application is crucial but yet challenging. Herein, carbon shells are introduced to Pt/CeO to inhibit the deactivation caused by SO for CO oxidation. The chemical properties and catalytic activity indicate that Pt/CeO@C effectively sustains the valence state of Pt species and exhibits T of 180 °C for CO oxidation in the presence of SO and HO. This approach provides a new perspective for enhancing the SO tolerance of catalysts for exhaust treatment.

通过碳涂层增强 Pt/CeO2 催化剂用于 CO 氧化的 SO2 耐受性

开发工业应用的耐硫催化剂至关重要，但也具有挑战性。在此，将碳壳引入到Pt/CeO中以抑制SO对CO氧化造成的失活。化学性质和催化活性表明，Pt/CeO@C 有效地维持了 Pt 物质的价态，并在 SO 和 H2O 存在下表现出 180 °C 的 CO 氧化温度。该方法为提高废气处理催化剂的SO耐受性提供了新的视角。
