Metal 3D Printed Nickel-Based Self-Catalytic Reactor for COx Methanation

3D printing technology can rapidly transform digital model into physical realization, and has been widely studied in many fields. However, its developments are very slow in the fields of catalysis and reaction engineering, due to harsh application environments. Here, we report that metal 3D printing is used to prepare Nickel-based Self-Catalytic Reactor (Ni-SCR) for COx methanation. The optimized Ni-SCR samples exhibit unique surface properties. The catalytic results reveal that they also possess premium methanation performance. This work will facilitate the developments both in 3D printing technologies and novel catalytic systems.
