Many 2D graphene-based catalysts for electrooxidation of glucose involved the use of binders and toxic reducing agents in the preparation of the electrodes, which potentially causes the masking of original activity of the electrocatalysts. In this study, a green method was developed to prepare binder-free 3D graphene aerogel/nickel foam electrodes in which bimetallic Pd-Pt NP alloy with different at% ratios were loaded on 3D graphene aerogel. The influence of Pd/Pt ratio (at%: 1:2.9, 1:1.31, 1:1.03), glucose concentration (30 mM, 75 mM, 300 mM, 500 mM) and NaOH concentration (0.1 M, 1 M) on electrooxidation of glucose were investigated. The catalytic activity of the electrodes was enhanced with increasing the Pd/Pt ratio from 1:2.9 to 1:1.03, and changing the NaOH/glucose concentration from 75 mM glucose/0.1 M NaOH to 300 mM glucose/1 M NaOH. The Pd₁Pt_1.03/GA/NF electrode achieved a high current density of 388.59 A g⁻¹ under the 300 mM glucose/1 M NaOH condition. The stability of the electrodes was also evaluated over 1000 cycles. This study demonstrated that the Pd₁Pt_1.03/GA/NF electrode could be used as an anodic electrode in glucose-based fuel cells.

用于葡萄糖电氧化的许多2D石墨烯基催化剂涉及在电极的制备中使用粘合剂和有毒还原剂，这有可能导致掩盖电催化剂的原始活性。在这项研究中，开发了一种绿色方法来制备无粘合剂的3D石墨烯气凝胶/镍泡沫电极，其中将具有不同at％比率的双金属Pd-Pt NP合金负载在3D石墨烯气凝胶上。Pd / Pt比（at％：1：2.9，1：1.31，1：1.03），葡萄糖浓度（30 mM，75 mM，300 mM，500 mM）和NaOH浓度（0.1 M，1 M）的影响研究了葡萄糖的电氧化。通过将Pd / Pt比从1：2.9增加到1：1.03，并将NaOH /葡萄糖浓度从75 mM葡萄糖/0.1 M NaOH更改为300 mM葡萄糖/ 1 M NaOH，可以增强电极的催化活性。₁ Pt _1.03 / GA / NF电极在300 mM葡萄糖/ 1 M NaOH条件下获得了388.59 A g ^-1的高电流密度。还在1000次循环中评估了电极的稳定性。这项研究表明，Pd ₁ Pt _1.03 / GA / NF电极可用作葡萄糖基燃料电池中的阳极电极。
