Abstract

This disclosure provides methods of making an enhanced activity nanostructured thin film catalyst by radiation annealing, typically laser annealing, typically under inert atmosphere. Typically the inert gas has a residual oxygen level of 100 ppm. Typically the irradiation has an incident energy fluence of at least 30 mJ/mm2. In some embodiments, the radiation annealing is accomplished by laser annealing. In some embodiments, the nanostructured thin film catalyst is provided on a continuous web.
