Efficient photoactivated hydrogen evolution promoted by Cu_xO-gCN-TiO₂-Au (x = 1,2) nanoarchitectures.

ABSTRACT: In this work, we propose an original and potentially scalable synthetic route for the fabrication of Cu_xO-gCN-TiO₂-Au (x = 1,2) nanoarchitectures, based on Cu foam anodization, graphitic carbon nitride liquid-phase deposition, and TiO₂/Au sputtering. A thorough chemico-physical characterization by complementary analytical tools revealed the formation of nanoarchitectures featuring an intimate contact between the system components and a high dispersion of gold nanoparticles. Modulation of single component interplay yielded excellent functional performances in photoactivated hydrogen evolution, corresponding to a photocurrent of ≈-5.7 mA cm^-2 at 0.0 V vs. the reversible hydrogen electrode (RHE). These features, along with the v
