Research Progress in Functionalization of 3D-Printed Monolithic Catalytic Material and Its Application in Enhancing Reaction Mass Transfer
Three-dimensional(3D)printing is a digital design and manufacturing process that can simplify multidimensional manufacturing by two-dimensional superposition of materials from bottom to top.Importantly,it has the potential to overcome the limitations of traditional catalytic material molding processes,thus significantly reducing the complexity involved in manufacturing geometrically intricate and monolithic catalytic materials.For these materials,the selection of functional processing methods and geometric designs is crucial for achieving optimal catalytic performance.The research progress in functionalization approach for 3D-printed monolithic catalytic materials and their applications in mass transfer enhancement are reviewed,the technical characteristics of conventional modeling process and 3D printing molding process for monolithic catalytic materials are discussed.Additionally,an overview of preparation strategies for direct and post-treatment functionalization(including coating and secondary growth methods)of 3D-printed monolithic catalytic materials is presented,and the influence of geometric configurations of 3D-printed monolithic catalytic materials on reaction mass transfer is further analyzed.These aim to provide valuable insights for the development of high-performance 3D-printed monolithic catalytic materials.
