Major Contributions
 

1. A molecular bottom-up approach designs a bimetallic Cu-Pd single-site catalyst (SSC) with CuN₄/PdN₄ moieties, achieving 83% Faradaic efficiency for formate and 16% for C3 products in glycerol electrooxidation (GOR) at 1.0 V vs. RHE.

2. Operando spectroscopy and DFT reveal that Pd sites facilitate C-OH adsorption, preventing C-C bond cleavage and catalyst poisoning by CO/CO₃²⁻, while the synergistic CuN₄/PdN₄ coordination governs product selectivity.

3. The catalyst maintains stable performance for 144 h at 50 mA cm⁻², validating the SSC design as a selective and durable strategy for producing value-added formate and C3 chemicals from biomass-derived glycerol.

主要貢獻
 

1. 以分子自下而上方法設計具有 CuN₄/PdN₄ 配位的雙金屬 Cu-Pd 單位點催化劑，在甘油電氧化（GOR）中於 1.0 V vs. RHE 實現甲酸鹽法拉第效率 83%、C3 產物 16%。

2. 原位光譜與 DFT 揭示 Pd 位點促進 C-OH 吸附，防止 C-C 鍵斷裂與 CO/CO₃²⁻ 催化劑中毒，CuN₄/PdN₄ 協同配位決定產物選擇性。

3. 催化劑在 50 mA cm⁻² 下穩定運行 144 小時，驗證 SSC 設計是從生質衍生甘油生產增值甲酸鹽與 C3 化學品的選擇性持久策略。
