Abstract The development of advanced electrocatalysts for the abiotic direct glucose fuel cells (ADGFCs) is critical in implantable devices living organisms. ligand effect Pt shell‐alloy core nanocatalysts known to influence electrocatalytic reaction interfacial structure. Herein, we reported synthesis ternary Pt@PdRu nanoalloy aerogels with PdRu on Pt‐enriched surface through electrochemical cycling. optimized electronic structure exhibited high mass activity and specific about 450 mA mg −1 1.09 cm −2 , which were 1.4 1.6 times than that commercial Pt/C. Meanwhile, have higher stability comparable In‐situ FTIR spectra results proved oxidation followed CO‐free pathway mechanism part products are CO 2 by completed oxidation. Furthermore, ADGFC ultrathin anode catalyst layer showed a much power density 6.2 mW Pt/C (3.8 Mw ). To simulate blood cell, integrated membrane electrode assembly was exposed solution steady‐state open circuit approximately 0.6 V achieved optimizing concentration cell system.
