Review of 3D printing in photocatalytic substrates and catalysts

3D printing of cellulose/leaf-like zeolitic imidazolate frameworks (CelloZIF-L) for adsorption of carbon dioxide (CO2) and heavy metal ions

“…The synthesis method in ref. 12 was used to synthesize TEMPO-oxidized cellulose nanofibers (TOCNF) using spruce cellulose pulp (Domsjö Fabriker AB, Sweden, never-dried form, 17 wt.%).…”

“…Three-dimensional (3D) printing technologies have become cheaper, and one can find suitable 3D printers for less than €500. [1][2][3][4] They have advanced several applications, including biomedical applications, 5 regenerative medicine, 6,7 tissue engineering, [8][9][10] wound healing, 11 photocatalysis, 12 and water treatment. 13 3D printing can be achieved via several methods including fused deposition modeling (FDM) printing 1 and direct ink writing (DIW or robocasting).…”

3D‐Architected Alkaline‐Earth Perovskites

“…Those characteristics are of importance in the field of reaction chemistry, such as photocatalysis. [72,73] Although BZO, CZO, and SZO reveal optically the presence of oxygen deficiencies, the optical response is attributed to local inhomogeneities in our alkaline-perovskite microarchitectures, we can expect that longer annealing times to reduce background emissions from defects for the production of refractive index ceramics in micro-optics. [8,28] Our group has observed similar findings for low-temperature annealing (≈600 °C) of denser ZrO 2 ceramics, [24] which could have caused the buried of carbon or non-stochiometric components, [42] as could be the case for nonstoichiometric BZO, CZO, and SZO species.…”

Deployable and Retrievable 3D-Printed Zeolite–Polymer Composites for Wastewater Treatment: A Review

“…This method has good manufacturing accuracy in controlling channel size, fiber thickness, and channel geometry. 3DFD in general can be categorized as a material extrudate method on the basis of direct ink writing, with the porous materials would be produced from extruded fibers with a high viscous paste . 3DFD produce a highly reproducible and periodic structure include the process variables like the nozzle opening (fiber thickness), the type of nozzle (fiber shape), the interfiber distance (pore size), and the stacking of the layers (porous architecture) .…”
