3D printing in photocatalysis: Methods and capabilities for the improved performance

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.…”

“…Addition-ally, BZO powder reveals the loss of the 3.9 eV emission previously assigned to shallow trap states. Besides the spatial organization offered by 3D printing, which can enable the control of (photo)chemical reaction performance [72,73] or light-matter interaction in optics and photonics. [22] Defective and disordered BZO 3D microarchitectures can be treated as oxygen-deficient systems, which hold important applications in electrochemistry.…”

High-Efficiency Photocatalytic Reactors Fabricated via Rapid DLP 3D Printing: Enhanced Dye Photodegradation with Optimized TiO2 Loading and Structural Design

“…3D printing technology offers new methods to manufacture carriers with any structure and even directly print heterogeneous catalysts, simplifying preparation and optimizing reactor structure and kinetics, especially beneficial for photocatalytic reactors. 15 A Scopus database search for "[TITLE-ABS-KEY ("3D printing" OR "additive manufacturing") AND TITLE-ABS-KEY ("photocatalytic" OR "photocatalysts" OR "photocatalysis" OR "photoreactor")]" shows that research on directly 3D printing photocatalytic reactors began in 2016. Hartings and co-workers were the first to propose mixing acrylonitrile butadiene styrene (ABS) with TiO 2 nanoparticles and extruding them into filaments, 16 then printing TiO 2 -ABS nanocomposites with a fused-deposition modeling (FDM) 3D printer, while also verifying their capability for photodegrading Rhodamine 6G in water.…”
