Upcycling secondary waste materials into topologically-optimized hierarchically porous composites to tailor the electrochemical degradation pathway of persistent organic pollutants

This project aims to realize smart assemblies of hierarchical carbon nanoarchitectures as tailored electrochemical interfaces, by upcycling secondary waste materials (SWM) as fillers and catalysts. Thanks to a novel approach, combining additive manufacturing with a controlled phase-inversion method, it is possible to realize the macroscopic structure of the carbon electrode, topologically optimized by CFD simulation. The further treatment by microwave plasma-enhanced chemical vapor deposition allows tailoring the surface with various nanostructures, such as doped-diamonds, carbon nanowalls, nanotubes and other exotic allotropes, due to the presence of metal impurities in the SWM. Indeed, the hierarchical macro-meso-microporous carbon electrode is expected to exhibit higher surface area, superior charge and mass transfer efficiencies and, at the same time, the plasma treatment limits the potential leaching of metals from the composite. The morphological, chemical and electrochemical characterization will be performed for the synthesized heterostructures. Finally, carbon nanoarchitectures will be tested as hybrid electrodes for removing water pollutants of actual concern. Shape and features at each scale will be tailored to optimize the process and the collected data will be analyzed by multivariate techniques to elucidate the relationships between the material features, specifically as it relates to the understanding of the intrinsic properties. This will result in scientific publications and know-how. It is planned to employ young scientific personnel and increase the research and measurement infrastructure of GUT.

Metal and metal oxide particles are abundant in various ash-based wastes. Utilizing these as catalyst sources for the fabrication of carbon nanomaterials could present a valuable approach to reduce our reliance on non-renewable and costly catalyst sources, thereby facilitating large-scale nanomaterial production. In this context, secondary waste materials (SWMs) are by-products resulting from the (complete or partial) combustion...

Tailoring the defects in graphene and its related carbon allotropes has great potential to exploit their enhanced electrochemical properties for energy applications, environmental remediation, and sensing. Vertical graphene, also known as carbon nanowalls (CNWs), exhibits a large surface area, enhanced charge transfer capability, and high defect density, making it suitable for a wide range of emerging applications. However, precise...
