Direct glucose fuel cells (DGFCs) received great interest due to non-toxicity, low cost, and renewability. Herein, we demonstrated the synthesis of novel porous AuPtPd nanocrystals (NCs) via plausible one-pot synthesis route. This was implemented by reduction of the metal precursors with l-ascorbic acid in the presence of polyvinylpyrrolidone (PVP) as a structure-directing agent. TEM (transmission electron microscopy) images of the as-synthesized nanocrystals depicted porous nanodendritic morphology with particle size ranging from 20 to 30 nm. The catalytic performance of AuPtPd NCs was investigated towards glucose oxidation reaction (GOR) in alkaline medium compared to AuPt, PtPd, and Pt/C. The delivered maximum oxidation current density over AuPtPd was 10.1 mA cm⁻², which is nearly 1.4, 1.8, and 3.5 times greater than AuPt, PtPd, and Pt/C, respectively. Additionally, the ternary electrocatalyst exhibited higher electrochemical stability compared to binary alloys and Pt/C counterparts. Furthermore, AuPtPd revealed lower Tafel slope for GOR compared to binary alloys and Pt/C which affirm enhanced GOR kinetics. The outstanding catalytic performance of AuPtPd NCs was attributed to the synergistic effect of the alloying elements and the high anti-poisoning effect of Au and Pd metals which facilitates the adsorption of surface hydroxyls (OH)_ads on the catalyst active sites and enhances the oxidation kinetics.

直接葡萄糖燃料电池（DGFC）由于无毒，低成本和可再生性而引起了人们的极大兴趣。在这里，我们展示了通过合理的一锅合成路线合成新型多孔AuPtPd纳米晶体（NCs）。这是通过在聚乙烯吡咯烷酮（PVP）作为结构导向剂的存在下用1-抗坏血酸还原金属前体来实现的。合成后的纳米晶体的TEM（透射电子显微镜）图像显示了多孔纳米树突形态，粒径范围为20至30 nm。与AuPt，PtPd和Pt / C相比，研究了AuPtPd NCs在碱性介质中对葡萄糖氧化反应（GOR）的催化性能。在AuPtPd上传递的最大氧化电流密度为10.1 mA cm ^-2，分别是AuPt，PtPd和Pt / C的近1.4倍，1.8倍和3.5倍。另外，与二元合金和Pt / C对应物相比，三元电催化剂具有更高的电化学稳定性。此外，与二元合金和Pt / C相比，AuPtPd显示出较低的Tafel斜率，证实了增强的GOR动力学。AuPtPd NCs的出色催化性能归因于合金元素的协同​​作用以及Au和Pd金属的高抗毒作用，这有助于表面羟基（OH）_广告吸附在催化剂活性位上并增强氧化动力学。
