3D-Printed Boron-Nitrogen Doped Carbon Electrodes for Sustainable Wastewater Treatment via MPECVD.

ABSTRACT: This study proposes a novel and sustainable method for fabricating 3D-printed carbon-based electrodes for electrochemical wastewater treatment. We prepared B,N-doped carbon electrodes with hierarchical porosity and a significantly enhanced surface area-to-volume ratio (up to 180%) compared to non-optimized analogues using a synergistic combination of 3D printing, phase inversion, and microwave plasma-enhanced chemical vapor deposition. This process allows the metal-free growth of vertically aligned carbon nanostructures directly onto polymer-derived substrates, resulting in a 20-fold increase in the electrochemically active surface area. Computational fluid dynamics simulations were used to improve mass transport and reduce pressure drop. Electrochemical characterization demonstrated that
