Description:
A Catalan Research group specialized in nanoengineering has developed an industrial process to obtain mesoporous metallic alloys films.

This kind of film can be used as lightweight materials for aeronautic applications, implants, catalytic and electro catalytic applications.

Most of the current techniques are two-step based. These synthesis are not cost-effective, relatively slow and, quite often, require from advanced technologies.

The existing synthetic techniques that allow to obtain metallic porous layers in a single-step use hydrogen bubbles formed during cathodic electrodeposition as a dynamic template. Consequently, the generated pores have micrometer sizes, the size of the pore being determined by the size of the generated bubbles. Thus, these one-step techniques are not suitable to fabricate mesoporous metallic films with pore sizes below 50 nm.

The present invention provides novel magnetic-electrocatalytic, pseudo-ordered mesoporous alloy films, wherein the alloy is a metallic binary alloy (e.g., FePt or CuNi), in which at least one of the two constituent elements is a non-noble transition metal, leading to a more economic material.

Advantageously, the new porous metallic binary alloy films have a pore size ranging between 2 and 50 nm, in which the porosity is pseudo-ordered, with magnetic and electro catalytic properties.

The magnetic-electro catalytic, pseudo-ordered mesoporous alloy films, according to the invention, are supported on the surface of a conductive substrate.

The thin-film geometry onto a conductive substrate allows for an easy manipulation of the mesoporous alloy films and it does not require subsequent immobilization on a substrate as it is the case in mesoporous powders wherein such immobilization is indispensable for applications like electro catalysis.

The group is looking for a company interested in a licensing agreement, willing to apply this industrial process.
Advantages and Innovations:
- Cost-effective one-step synthesis which can be
industrially scalable.
- Mesoporous metallic films with pores between 2- 50 nm.
- Successfully applied to the synthesis of mesoporous
metallic layers consisting of pure metals.
- Pseudo-ordered pores - suitable for applications
based on "magnetic antidots".
- Magnetic and electrocatalytic properties.
- Oxidation of the metals present in the alloy has been
highly reduced or almost prevented.
- The films are supported on the surface of a conductive
substrate
