Formation of PdPtRuRhIrTe multicomponent nanowire aerogels
 

Major Contributions
 

1. Developed a "confined topological transformation" strategy to directly fabricate multicomponent nanowire aerogels (MNWAs), and uncovered a "confined interfacial bonding evolution competition mechanism" governing noble metal interactions with Te templates.

2. PdPtRuRhIrTe MNWAs/C delivered a Faradaic efficiency of 91.7% and a yield rate of 12.05 mmol h⁻¹ mg⁻¹ for glycolic acid in PET-derived ethylene glycol oxidation, and operated stably for over 1000 h at 100 mA cm⁻² in a membrane electrode assembly.

3. Revealed that the multicomponent synergistic effect promotes electron and mass transfer and balances *OH and ethylene glycol adsorption, lowering the energy barrier of the potential-determining step.




主要貢獻
 

1. 提出「受限拓撲轉化」策略直接合成多元奈米線氣凝膠(MNWAs),並揭示貴金屬與碲模板之間的「受限界面鍵結演化競爭機制」。

2. PdPtRuRhIrTe MNWAs/C 於 PET 衍生乙二醇氧化反應中,生成乙醇酸的法拉第效率達 91.7%、產率達 12.05 mmol h⁻¹ mg⁻¹,並在膜電極組中於 100 mA cm⁻² 穩定運轉超過 1000 小時。

3. 分析與理論計算顯示,多元金屬的協同效應可促進電子與質量傳輸,並平衡 *OH 與乙二醇的吸附,降低決速步驟的能障。
