Metal/TiO2 composite photocatalysts with tunable activity for nitrogen fixation: the impact of metal nanoparticles

Metal-loaded TiO 2 (M-TiO 2 , M = Au, Pd, Cu) composites were constructed and applied in photocatalytic nitrogen fixation. It has been found that the status of Cu 2+ , as a generic interacial mediator, was conducive to the catalytic performances.
