Highly efficient activation of sulfite with robust Mn-MOF catalysts for arsenite oxidation: Formation and contribution of Mn(V)

Key Points

• Arsenite oxidation effectiveness increases significantly with manganese-based catalysts, leading to efficient removal.
• Catalytic activity is primarily linked to the formation of manganese(V) species during the oxidation process.
• Investigation utilizes manganese metal-organic frameworks (Mn-MOF) to study their catalytic properties in detail.
• Findings highlight the potential of these catalysts in environmental applications, particularly in arsenic contamination removal.
