Abstract

The integration of 3D printing technology into catalytic water treatment has opened new avenues for designing advanced catalysts with customized structures and functionalities. However, a comprehensive review of how 3D-printed catalysts enhance performance, stability, and efficiency across different oxidation systems remains lacking. This review addresses that gap by summarizing recent advancements in 3D-printed catalysts for advanced oxidation processes, including Fenton-like reactions, photocatalysis, and electrocatalysis. Key aspects such as material composition, structural design, and fabrication techniques are critically evaluated. Notably, 3D-printed catalysts used in Fenton-like and photocatalytic processes benefit from improved mass transfer and enhanced active site exposure, leading to more efficient pollutant degradation. Additionally, iron- and non-metallic-based catalysts, particularly those with triply periodic minimal surface (TPMS) structures, demonstrate superior oxidation performance. The incorporation of visible light-responsive materials such as BiVO₄ and g-C₃N₄ further boosts catalytic activity under natural sunlight. These insights pave the way for the development of more efficient and sustainable catalysts, supporting global environmental goals and promoting the adoption of 3D printing technologies in industrial applications. These insights contribute to the development of efficient and eco-friendly catalytic systems, supporting global sustainability goals and promoting the broader adoption of 3D printing technologies in industrial water treatment applications.Despite extensive research on catalytic water treatment, a systematic evaluation of the role of 3D-printed catalysts in optimizing reaction efficiency, stability, and reusability remains lacking. This review aims to fill this gap by critically analyzing the materials, structural designs, and fabrication techniques of 3D-printed catalysts and evaluating their impact on Fenton-like oxidation, photocatalysis, and electrocatalysis.

期刊介绍： Separation and Purification Technology is a premier journal committed to sharing innovative methods for separation and purification in chemical and environmental engineering, encompassing both homogeneous solutions and heterogeneous mixtures. Our scope includes the separation and/or purification of liquids, vapors, and gases, as well as carbon capture and separation techniques. However, it's important to note that methods solely intended for analytical purposes are not within the scope of the journal. Additionally, disciplines such as soil science, polymer science, and metallurgy fall outside the purview of Separation and Purification Technology. Join us in advancing the field of separation and purification methods for sustainable solutions in chemical and environmental engineering.
