Porous Transport Layers: Exploring the Interface of Skin‐Layered Titanium Fibers for Electrochemical Water Splitting (Adv. Energy Mater. 8/2021)

In article number 2002926, Marcelo Carmo and co-workers use a very simple and scalable method to protect titanium porous transport layers (PTLs) from passivation by sputtering very thin layers of Ir or Pt onto PTLs. 4000 h stable durability profiles are achieved when PTLs are coated with only 0.1 mg cm−2 of Pt or Ir. The results of this work show how the interface of a well-protected titanium fiber behaves against passivation after long-term operation under real electrolysis conditions.
