| Abstract: | Here, we report the use of highly reproducible free-standing 3D Pt nanowire frameworks (3D Pt NFs) to investigate the electrochemical oxidation of glucose. To create this unique Pt NFs, we utilize a lipidic bicontinuous cubic phase as a template. The resulting Pt NFs exhibits a unique 3D single diamond morphology with Fd3m symmetry. This intricate structure provides a large surface area and high electrocatalytic efficiency, making it more sensitive to glucose detection. Small Angle X-ray Scattering and Transmission electron microscopy investigations provided valuable insights into the nanoarchitecture of 3D Pt NFs. It highlights the interconnected nature of the nanowires and showcases the potential for optimized electrochemical performance. Very high current densities are registered for the glucose oxidation reactions at 3D Pt NFs during cyclic voltammetry investigations. This knowledge aids in the design and development of advanced electrocatalytic systems, fuel cells, biosensors, and other devices that leverage the unique characteristics of the 3D Pt framework. This study explores 3D Pt NFs for electrochemical glucose oxidation. Using a phytantriol template with two non-intersecting aqueous channels (A), Pt is electrodeposited in one channel (B), resulting in the formation of 3D Pt NFs after template washing (C). This approach demonstrates the potential for efficient glucose oxidation in the structured nanowire frameworks. [ABSTRACT FROM AUTHOR] |
