C-C bond cleavage during electrocatalytic oxidation of glycerol and C₃₊ polyols often occurs and can significantly affect the Faradaic efficiency, fuel utilization, and output power density of a direct polyol fuel cell, although this has not been deeply investigated. With the goal of acquiring new knowledge of C-C bond breaking of polyols, this study examines the electrocatalytic oxidation of a C₄ polyol meso-erythritol on carbon nanotube supported Pd-based catalysts (Pd/CNT, PdAg/CNT, and PdAg₃/CNT) in an anion-exchange membrane fuel cell (AEMFC). Our results show that PdAg/CNT improves the fuel efficiency of meso-erythritol oxidation by contributing to the C-C bond cleavage of meso-erythritol in C₃ and C₂ chemicals. Based on the analysis of electro-oxidation products and half-cell cyclic voltammetry (CV) of intermediates, a meso-erythritol electro-oxidation pathway has been proposed to demonstrate that Ag is likely to assist Pd to promote the cleavage of C-C bonds of meso-erythritol.

在甘油和C ₃₊多元醇的电催化氧化过程中，经常发生CC键断裂，并且可以显着影响直接多元醇燃料电池的法拉第效率，燃料利用率和输出功率密度，尽管尚未对此进行深入研究。为了获得新的多元醇CC键断裂知识，本研究研究了碳纳米管负载的Pd基催化剂（Pd / CNT，PdAg / CNT和PdAg ₃ / CNT）上C ₄多元醇中赤藓糖醇的电催化氧化。）装在阴离子交换膜燃料电池（AEMFC）中。我们的结果表明，PdAg / CNT通过促进C ₃和C _2中中赤藓糖醇的CC键裂解，提高了中赤藓糖醇氧化的燃料效率。化学药品。基于对中间体的电氧化产物和半电池循环伏安法（CV）的分析，提出了中赤藓糖醇电氧化途径，以证明Ag可能有助于Pd促进内消旋CC键的裂解。 -赤藓糖醇。
