A system investigation on Ru-MOF-74 with efficient photocatalytic nitrogen fixation performance

Developing highly efficient photocatalysts for nitrogen fixation into ammonia is of great importance for solving the energy crisis and sustainable development. In this work, we report a simple synthesis of Ru 3+ ions modified MOF-74 nanostructures . These Ru 3+ ions are introduced into the internal channels of MOF-74 structure. The photocatalytic activity of nitrogen fixation was remarkably improved under visible irradiation (λ > 400 nm). After the introduction of Ru 3+ ions, the visible response is enhanced and the photo-excited charge carriers are separated and transferred to the surface efficiently, leading to an improved photocatalytic performance. This work may offer a better understanding for designing and developing MOFs photocatalysts with high performance and low cost.
