Photo- and thermal catalysis of nitrate to nitrite by manganese ions under light up to 600 nm

Key Points

• Reduction of nitrate to nitrite occurred using manganese ions as a catalyst under light exposure, along with phenol degradation.
• Key finding includes the transformation of nitrate to nitrite in the presence of manganese ions under light.
• Observational analysis under UV and visible light up to 600 nm reveals effective catalysis by manganese ions.
• Supports methods for reducing nitrate levels and degrading persistent organic compounds in environmental settings.
