Enhanced photocatalytic nitrogen fixation on defects regulated Ni-doped MIL-101(Fe) via nitrogen coordinated activation

Key Points

• The central aim is to improve the efficiency of nitrogen fixation through defect engineering in Ni-doped MIL-101(Fe).
• Synthesize Ni-doped MIL-101(Fe) with varying oxygen vacancy concentrations.
• Investigate photocatalytic performance for nitrogen fixation.
• Analyze charge recombination rates.
• Defect concentration positively correlates with enhanced nitrogen fixation efficiency.
• Significant reduction in charge recombination observed in optimized samples.
• Establishment of a nitrogen coordinated activation mechanism.
