Abstract

In this study, a novel nonenzymatic glucose fuel cell (GFC) based on an anode of gold nanoparticles (AuNPs) deposited on a nanohemisphere array (NHA) is proposed. The novelty of the proposed GFC is a nanostructured anode with a few AuNPs uniformly deposited on an NHA of polyethylene terephthalate (PET). The NHA of PET is fabricated using nano-imprinting with a Ni mold that is electroformed using a barrier layer on an anodic aluminum oxide as a template. AuNPs are then electrochemically deposited on the surface of the NHA. The cathode consists of graphene oxide deposited on a glassy carbon electrode. A Nafion thin film acts as a proton exchange membrane to effectively separate the anode and cathode compartments. Experimental results demonstrate that the proposed nonenzymatic GFC achieves a power density of 2.05 mW/cm², a current density of 5.6 mA/cm², and an open-circuit voltage of 0.66 V. Notably, the advantages of this GFC include its enzyme-free operation, ease of production, low cost, and high repeatability. Consequently, it holds significant promise for commercialization and practical applications.

以金纳米粒子为阳极沉积在纳米印迹聚对苯二甲酸乙二醇酯纳米半球阵列上的非酶葡萄糖燃料电池

在这项研究中，提出了一种基于纳米半球阵列（NHA）上沉积的金纳米颗粒（AuNPs）阳极的新型非酶葡萄糖燃料电池（GFC）。所提出的GFC的新颖之处在于，它是一种纳米结构的阳极，其中一些aunp均匀地沉积在聚对苯二甲酸乙二醇酯（PET）的NHA上。PET的NHA采用纳米压印技术，在阳极氧化铝上使用阻挡层作为模板电铸镍模。然后，aunp通过电化学沉积在NHA表面。阴极由沉积在玻碳电极上的氧化石墨烯组成。Nafion薄膜作为质子交换膜，有效地分离阳极和阴极隔室。实验结果表明，该无酶GFC的功率密度为2.05 mW/cm²，电流密度为5.6 mA/cm²，开路电压为0.66 V。值得注意的是，该GFC的优点包括无酶操作、易于生产、低成本和高重复性。因此，它在商业化和实际应用方面具有重要的前景。
