3D Printing of Artificial Leaf with Tunable Hierarchical Porosity for CO₂ Photoreduction

The development of new pathways for 3D artificial photosynthetic systems (APS) with controllable architectures and tunable hierarchical porosity on a large scale is significant. Herein, we demonstrate a 3D printing approach for fabricating artificial microleaves with 3D architectures spanning orders of magnitude from nanometers to centimeters in a rapid, programmable, and scalable manner. TiO2-based inks served as a preliminary prototype, with...
