Herein, carbon nanotube (CNT) supported ruthenium (Ru), iridium (Ir), and copper (Cu) catalysts at 0.1 to 20 wt% metal loading are prepared by the NaBH4 reduction method for glucose electrooxidation reaction (GER). These catalysts are successfully characterized by X‐ray diffraction, scanning electron microscope, and N2 adsorption‐desorption measurements. Voltammetric measurements of these catalysts are taken using cyclic voltammetry and chronoamperometry techniques. The crystallite sizes of these catalysts are calculated as 2.53 nm for Ru/CNT, 2.94 nm for Ir/CNT, and 13.06 nm for Cu/CNT by using Scherrer equation. For GER, 10% Ru/CNT, 0.1% Ir/CNT, and 0.5% Cu/CNT catalysts have high current densities as 1.86 mA cm−2 (160.6 mA mg−1 Ru), 3.03 mA cm−2 (23 857.2 mA mg−1 Ir), and 1.12 mA cm−2 (1768.8 mA mg−1 Cu), respectively. These catalysts have also good stability. Results reveal that 10% Ru/CNT, 0.1% Ir/CNT, and 0.5% Cu/CNT catalysts are promising catalysts as direct glucose fuel cell anode catalysts.

“…Metal-based nanozymes have been frequently anchored on carbon-based materials, particularly carbon nanotubes and graphene oxide (GO), to construct the electrodes of NBFC, owing to their advantageous characteristics as a support material such as excellent conductivity, large surface area, biocompatibility, insignificant mass, and possibility to tailor the catalytic activity and specificity toward a certain substrate. For example, Irfan et al [ 64 ] designed a glucose biofuel cell including an anodic electrode made from a Ni/Co composite anchored on reduced GO (rGO), with a cathodic electrode made from Cu 2 O. Compared with Ni-rGO and Co-rGO, Ni/Co-rGO significantly improved the catalytic activity of glucose oxidation because of the synergistic effect of Ni, Co, and rGO.…”

The appearance and evolution of biofuel cells can be categorized into three groups: microbial biofuel cells (MBFCs), enzymatic biofuel cells (EBFCs), and enzyme-like nanomaterial (nanozyme)-based biofuel cells (NBFCs). MBFCs can produce electricity from waste; however, they have significantly low power output as well as difficulty in controlling electron transfer and microbial growth. EBFCs are more productive in generating electricity with the assistance of natural enzymes, but their vulnerability under diverse environmental conditions has critically hindered practical applications. In contrast, because of the intrinsic advantages of nanozymes, such as high stability and robustness even in harsh conditions, low synthesis cost through facile scale-up, and tunable catalytic activity, NBFCs have attracted attention, particularly for developing wearable and implantable devices to generate electricity from glucose in the physiological fluids of plants, animals, and humans. In this review, recent studies on NBFCs, including the synthetic strategies and catalytic activities of metal and metal oxide-based nanozymes, the mechanism of electricity generation from glucose, and representative studies are reviewed and discussed. Current challenges and prospects for the utilization of nanozymes in glucose biofuel cells are also discussed.

“…The glucose fuel cell could be microbial, enzymatic, or abiotic. 31 An abiotic one is preferred due to its simplicity, stability and toughness. In abiotic cell, glucose is oxidized directly in alkaline medium.…”
