Practically applicable water oxidation electrodes from 3D-printed Ti6Al4V scaffolds with surface nanostructuration and iridium catalyst coating

A Mild Method for the Activation of Cation Exchange Membranes Used in Tubular PEM Electrolyzers

“…To prove that the pretreatment using triethylsilanol is milder than the one used for activating commercial membranes and does not lead to degradation of the electrode materials, the stability of the anodes was tested by storing anodic half‐cells in the pretreatment solutions. The anodic half‐cells used in this study are already reported by authors in [24] . Briefly, it consists of an additive manufactured Ti6Al4V (108 mm long, outer diameter 45 mm and wall thickness 0.75 mm) coated with 0.29 mg Ir cm −2 electrode.…”

“…The anodic half-cells used in this study are already reported by authors in. [24] Briefly, it consists of an additive manufactured Ti6Al4V (108 mm long, outer diameter 45 mm and wall thickness 0.75 mm) coated with 0.29 mg Ir cm À 2 electrode. The membrane with a thickness of 100 μm was extruded in the sulfonyl fluoride form directly onto this electrode.…”

Engineering 3D-printed carbon structures with atomic layer deposition coatings as photoelectrocatalysts for water splitting

“…5,[7][8][9][10][11] Several studies have utilized the core advantage of 3D-printing to manufacture tens to hundreds of hollow and solid cones on a at surface 7,8 and centimeter-scaled tubular metal electrodes. 12 In recent years, the fused deposition modeling (FDM) technique has emerged as a captivating alternative to produce carbon-composite electrodes. 13,14 FDM simplies the printing process with a benchtop printer or hand-held printing pen that is accessible in every research laboratory.…”

“…[18][19][20][21][22][23][24][25] Atomic layer deposition (ALD) that features conformal coating is presently the most feasible deposition technique to modify objects with geometrically complicated structures such as high porosity foams, 26,27 arrays of spheres, 28,29 tubes and channels. [30][31][32] Several studies have employed ALD to deposit an active material on 3Dprinted metal [10][11][12] and carbon electrodes. [20][21][22][23] However, for 3D carbon electrodes, the restriction on reaction temperatures and chemically inert carbon surface critically inuence the nucleation and initial growth of ALD processes, 20,23 posing limitations to depositing functional materials on carbon electrodes.…”
