Abstract

Highlights

A novel approach combining 3D printing, phase inversion, and microwave plasma-enhanced chemical vapor deposition is presented. This technique enables the creation of carbon-based electrodes with precise micro- and nanoscale control, offering potential for sustainable and high-performance wastewater treatment applications.
The synthesized 3D carbon scaffolds, enriched with B,N-doped carbon nanostructures, demonstrated superior performance in the electrochemical oxidation of β-blockers. Computational fluid dynamics simulations were used to optimize electrode design, leading to improved mass transport and reaction kinetics.
This research provides a sustainable and scalable solution for removing emerging contaminants from wastewater. The catalyst-free approach simplifies the fabrication process and reduces potential material contamination, making it a promising technology for advanced water 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.
