A synergistic interaction between isolated Au nanoparticles and oxygen vacancies in an amorphous black TiO2 nanoporous film: toward enhanced photoelectrochemical water splitting

We explore a strategy for significantly enhancing the photoelectrochemical water splitting efficiency by means of a synergistic interaction between plasmonic Au nanoparticles and oxygen vacancies in an amorphous black TiO₂ nanoporous film.
