Physical vapor deposition techniques are proposed as new ways to synthesize
mixed-metal oxides thin films as catalysts for the water oxidation
reaction. The search of efficient catalysts for the oxygen evolution
reaction is a key point to develop economically viable hydrogen production
technologies. Water oxidation catalysts based on abundant first-row
transition metals are currently studied in the scientific community since
they are cheap and environmentally friendly materials.
Simple and binary metal oxides thin films based on iron, cobalt and nickel
are currently under study in our laboratory, using Electron Beam Deposition
(EBD) technique.
The prepared samples are systematically studied through SEM microscopy,
Raman spectroscopy, and the electrochemical characterization of the
catalysts has been carried out to show the relevance of synergic effects of
mixed oxides in water oxidation reaction.

High power laser irradiation of pure metal targets has wide and relevant
applications such as Pulsed Laser Deposition (PLD) of metal-based
materials. The formation of nanoparticles in the laser ablation of metal
targets (with pulses ranging from nanoseconds to femtoseconds) is a complex
phenomenon, which involves competing ablation mechanisms and in-flight
interactions in the plasma plume expelled from the target.
Our study is focused on the phase explosion of the target's external
layers, which give rise to a mixture of vapor phase and liquid nanodroplets
directly produced within the target. Through a thermodynamic approach and a
Monte Carlo simulation we have been able to evaluate the material
composition immediately following the phase explosion and the size
distribution of the expelled nanodroplets.
