Progress of the development and application of 3D printing catalyst

与传统制备技术相比,3D打印技术在材料制备方面具有低成本、精度高和结构可控等优势,这使得3D打印技术在催化领域受到了广泛的关注。本文介绍了催化材料3D打印技术的最新进展,包括熔融沉积、光固化技术、直接墨水书写和选择性激光烧结技术。并对基于3D打印的聚合物、碳基材料、金属及氧化物基等材料在催化领域的应用进行了综述。文中指出,3D打印技术为催化剂的制备提供了一种新的途径,但在催化剂制备和应用方面仍存在打印速度慢、材料物理化学性质不稳定和使用范围受限等不足。本文提出了在材料种类拓展、催化剂结构优化、新型打印机与表面涂层技术研发等方面的未来发展方向。

Compared with traditional catalyst preparation techniques,3D printing has been gathered much attention due to the advantages of low cost,high accuracy and controllable structures.Recent progress of 3D printing technology in catalytic materials was introduced in this paper,including fused deposition modeling,stereo lithography appearance,direct ink writing and selective laser sintering.The catalytic applications of polymer,carbon-based materials,metal and oxide-based materials prepared by 3D printing techniques were reviewed.3D printing provides a new catalyst preparation way,but there were still shortcomings in the preparation and application,such as slow printing speed,unstable physical and chemical properties of materials,and limited application field.The directions for future development such as expanding material types,optimizing catalyst structures,new printers and surface coating technologies were proposed.
