Nanoporous layer-coated substrates
for electrocatalysis and gas sensing applications

Ready-to-test coated substrates ideal for rapid R&D and proof-of-concept studies.
 

We now offer on-demand nanoporous layer deposition service. Using our patented dry deposition technology, we deposit highly porous, homogeneous layers on substrate of choice to meet your specific application needs. 

These ready-to-test coated substrates are ideal for rapid R&D, proof-of-concept validation, and shortening development cycles in a variety of advanced applications, including electrocatalysis (PEMWE, CO₂RR, HER, OER, N₂RR) and gas sensing (CO₂, N₂, CO, NH₃, toluene, H₂).

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.

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.
