The present invention pertains to the field of nanoimprint lithography (NIL) processes and more specifically to a soft NIL process used for providing a sol-gel patterned layer on a substrate. Specifically, this process comprises a step of adjusting the solvent uptake of the sol-gel film to 10 to 50% vol., preferably between 15 and 40% vol., by varying the relative pressure of the solvent while a soft mould is applied onto the substrate coated with the sol-gel film.

The invention relates to a porous material in the form of microspheres based on iridium and/or iridium oxide, its preparation process, its use as anodic catalyst in a water electrolyser based on a solid polymer electrolyte, also called PEM water electrolyser (with PEM meaning 'Proton Exchange Membrane' or 'Polymer Electrolyte Membrane') or for the manufacture of light-emitting diodes for various electronic devices or for cars, and a PEM water electrolyser comprising such a material as an anode catalyst.
