- ... Photocatalytic systems capable of precisely regulating oxygen vacancy (OV) concentrations, which could help illuminate the effects of the OV concentration on N₂ fixation activity, are still scarce. Here, we demonstrate that excessive OVs in TiO₂, while increasing the adsorption activation capacity of N₂ molecules, exhibit disappointing activity due to a decrease in charge separation efficiency.
