Abstract The widespread application of green hydrogen production technologies requires cost reduction crucial elements. To achieve this, a viable pathway to reduce the iridium loading in proton exchange membrane water electrolysis (PEMWE) is explored. Herein, scalable synthesis method based on photodeposition process for TiO 2 @IrO x core–shell catalyst with reduced content as low 40 wt.% presented. Using this method, titania support particles homogeneously coated thin oxide shell only 2.1 ±...
We studied the acidifying efficiency of a cold atmospheric pressure plasma treatment and ambient air as working gas on lipid films. Acidification thin water film could be observed plasma-treated surfaces wool wax, pork sebum human lipids. This pH shift was partly attributable to NOx species formation nitric acid in upper layers substrates. The acidic compounds resulted shifts for up 2 h after exposure, which might beneficial pH-targeted therapies dermatology.
The porous‐transport layer (PTL) is a crucial component in proton‐exchange membrane water electrolyzers (PEMWE) enabling and gas transport as well electrically contacting the catalyst (CL). To reduce overall costs of PTLs, fabrication method by high‐velocity oxy‐fuel (HVOF) spraying introduced. Free‐standing PTLs are obtained via application titanium coating onto substrate its subsequent separation thermal treatment. feature two sides different roughness porosity analyzed visualized X‐ray...

Hydrogen as a promising energy carrier to bridge the gap between supply and demand of renewable energies can be produced by proton-exchange membrane water electrolysis (PEMWE). However, scarcity iridium limits widespread large-scale implementation PEMWE. Thus, state-of-the-art loading for oxygen evolution reaction (OER) ~1-2 mg Ir ·cm -2 must distinctly reduced. 1, 2 A decrease in involves reduction catalyst layer (CL) thickness. The is, however, only possible down certain threshold (≤ 0.5...
Proton-exchange membrane water electrolysis (PEMWE) is a promising technology for producing hydrogen from renewable energy sources. However, the high demand noble metals hinders widespread adoption of this technology. Especially anodic catalyst layer usually manufactured with loadings scarce element iridium, typically ~2 mg Ir ·cm -2 . As an active and stable noble-metal-free alternative to iridium catalysts has yet be developed, most viable strategy near future development PEMWE reduce as...
