\nWe have developed a new fabrication strategy for producing nanostructured CuO photocathodes based on the deposition of CuO nanoparticles generated by a sputter gas aggregation source, followed by an optimized thermal treatment. This approach enables precise control over the structural evolution of the nanoparticle films, promoting their recrystallization into highly crystalline CuO nanocubes with a porous architecture.<\/p>\n

 
\n 
\nThe resulting CuO nanostructured photocathodes exihibit photocurrent densities and an applied bias photon-to-current efficiencies that demonstrate excellent photoelectrochemical performance. Our results show that improved crystallinity enhances charge transport and suppresses electron\u2013hole recombination, highlighting the potential of this versatile fabrication route for photoelectrocatalytic and solar energy conversion applications.<\/p>\n
