The Au nanoparticles (with diameters around 5 nm) were synthesized by <i>in situ</i> reduction inside the porous structure of amorphous TiO<sub>2</sub> films with different pores sizes and pore arrangements. The effect of oxide thermal treatment, pore size, film thickness, and the amount of embedded Au nanoparticles on the catalytic activity was evaluated, using two different model reactions. The obtained results indicate that the proper selection of the oxide thermal treatment is key to obtain stable and durable composites, with a reproducible catalytic performance. Interestingly, several synthetic conditions led to equivalent catalytic activities. In particular, the film thickness and the total amount of Au particles did not significantly affect the reaction constants, indicating that the proportion of particles involved in the catalysis is low.

This review focuses on the influence of crystallographic phases on the electrochemical properties of LHs, a topic that remains relatively underexplored. We discuss several synthetic approaches that allow for precise tuning of these phases, along with the most suitable characterization techniques, including synchrotron-based methods, and highlight key spectroscopic features that aid in accurate phase identification. Additionally, we provide an overview of recent work from our group, which underscores the importance of crystallographic phases in shaping the electrochemical behaviour of LHs in alkaline environments, particularly for applications such as the oxygen evolution reaction.
