Nanocatalyst-Functionalized High-Density Nanofibers for Bio and Environmental Applications

Electrospinning has emerged as a transformative technique in the development of advanced nanomaterials, particularly for bio and environmental applications. Recent advancements have centered on the incorporation of nanocatalysts, including high-entropy and multi-elemental nanoparticles, onto high-density nanofiber supports, significantly enhancing catalytic efficiency for biological sensing and environmental remediation. These innovative materials address critical challenges in areas such as energy conversion, wastewater treatment, and air purification. Achieving stable immobilization of single-atom catalysts on robust nanostructures is essential to maintaining catalytic activity, preventing agglomeration, and optimizing performance with minimal catalyst loading.

This presentation will introduce the synthesis of nanocatalyst-functionalized and aligned nanofibers, offering tunable properties such as antibacterial activity and pollutant degradation capabilities. A case study will highlight the scalable production of functional nanofibers using custom-built, mass-production electrospinning systems, focusing on their application in separator membranes and air filtration technologies. Additionally, I will explore the development of biodegradable polymer-based nanofibers, demonstrating their potential as sustainable membrane materials in diverse applications. By integrating these high-performance, eco-friendly materials into real-world devices, this talk highlights the role of nanofiber technologies in driving advancements in bio and environmental fields.
