The ready-to-test coated substrates are ideal for rapid prototyping and proof-of-concept studies, facilitating a practical way to assess performance in your research workflow. Explore the customization options available to meet the practical needs of diverse application environments, including hydrogen production, electrocatalysis, and gas sensing.
Binder free
The dry manufacturing process generates ultra-pure coatings free of chemical contamination.
Low loadings
The reduced loading of coating materials supports both laboratory testing and scalable production.
High porosity
The large surface area increases the number of active sites for electrocatalysis or sensing.
Uniform thickness
The thickness uniformity of the coated layer facilitates efficient and controlled processes.
Iridium-coated titanium porous transport layers (PTLs)
Our iridium-coated PTLs are designed for durability in harsh operating conditions. With applications in water electrolysis, N2RR, and CO2RR, the coated PTLs are compatible with both experimental setups and industrial high-current-density environments.
