Article Synopsis
- Photocatalytic nitrogen fixation is an eco-friendly technology offering low energy consumption and potential for environmental protection, using specific catalysts designed for improved efficiency.
- The study focuses on two photocatalysts, Zr-NDC and Zr-BDC, showing that the structure of the organic ligands affects the charge density and the catalysts' performance in nitrogen reduction.
- Experimental results indicate that Zr-NDC outperforms Zr-BDC in nitrogen fixation efficiency (163.7 µmol gh vs. 29.3 µmol gh), demonstrating the potential of low-cost, non-toxic materials in advancing green chemistry.
Photocatalytic nitrogen fixation opens new opportunities for sustainable and healthier futures, and developing effective and inexpensive photocatalysts is the key. We use the ligand 3,3',5,5'-azomellitic acid (Habtc) to connect with Fe clusters and Zr clusters to form stable metal-organic frameworks (MOFs) Fe-abtc and Zr-abtc, both of which are responsive to visible lights for nitrogen fixation. It is worth noting that the presence of NN in the ligand makes it respond to visible lights.

The results indicated that increase in temperature led to an increase significantly and regularly in the toxicities of the four diamide insecticides against P. xylostella and H.
