Abstract:

Three-dimensional (3D) printing is a rapid prototyping technique. The applications of 3D printing for the preparation of catalyst and adsorbent have recently received increasing attentions. 3D printing can extend the range of monolithic catalysts and adsorbents, optimize the structure design and the active component distribution, which can enhance the mass and heat transfer during the catalytic reactions and adsorption processes. As a convenient and reliable modeling method, 3D printing is suitable for both laboratory operations and industrial applications. In this review, a general overview of the commonly available 3D printing methods is given for the preparation of catalysts and adsorbent. Recent works on printing strategies and new materials for catalysis and adsorption are also discussed. Polymers, carbon, metals and metal oxides, zeolites and many other materials can be incorporated into monolithic catalytic system by the help of 3D printing. The catalytic and adsorption performances can be controlled by the structure and distribution of the materials. Therefore, 3D printing is a promising technology for the preparation of catalysts and adsorbents. It is also pointed out that future developments have been discussed including the microstructure control of the material, the standardization of printing feedstocks and processes, and the design of the structures and active component distributions.
