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 the optimized electrodes performed significantly better, achieving 4.7-, 4-, and 6.5-fold increases in the degradation rates of atenolol, metoprolol, and propranolol, respectively, during electrochemical oxidation. These results highlight the efficacy of the integrated fabrication and simulation approach in producing high-performance electrodes for sustainable wastewater treatment applications.

3d打印硼氮掺杂碳电极通过MPECVD可持续废水处理。

本研究提出了一种新的、可持续的方法来制造用于电化学废水处理的3d打印碳基电极。与未优化的类似物相比，我们使用3D打印、相转化和微波等离子体增强化学气相沉积的协同组合制备了具有分层孔隙度和显着提高的表面积体积比（高达180%）的B， n掺杂碳电极。该工艺允许垂直排列的碳纳米结构直接在聚合物基板上无金属生长，导致电化学活性表面积增加20倍。采用计算流体力学模拟来改善质量传递和减小压降。电化学表征表明，优化后的电极性能明显更好，在电化学氧化过程中，阿替洛尔、美托洛尔和心得安的降解率分别提高了4.7倍、4倍和6.5倍。这些结果突出了集成制造和模拟方法在生产用于可持续废水处理应用的高性能电极方面的有效性。

期刊介绍： Nano-Micro Letters is a peer-reviewed, international, interdisciplinary, and open-access journal published under the SpringerOpen brand. Nano-Micro Letters focuses on the science, experiments, engineering, technologies, and applications of nano- or microscale structures and systems in various fields such as physics, chemistry, biology, material science, and pharmacy.It also explores the expanding interfaces between these fields. Nano-Micro Letters particularly emphasizes the bottom-up approach in the length scale from nano to micro. This approach is crucial for achieving industrial applications in nanotechnology, as it involves the assembly, modification, and control of nanostructures on a microscale.
