Dual Role of Azide as a Quencher and Stimulator of Singlet Oxygen Generation on Some Manganese Oxides

Key Points

• This research examines the dual role of sodium azide in both quenching and stimulating singlet oxygen generation using manganese oxides.
• Analyses of singlet oxygen production under various conditions with sodium azide present.
• Utilization of manganese oxides as catalysts for the reactions.
• Comparative measurements of 1O2 levels in both quenching and stimulating scenarios.
• Sodium azide significantly enhanced singlet oxygen production in the presence of manganese oxides.
• Observed a paradoxical effect where azide acted both as a quencher and stimulator of 1O2 generation.
• Conclusive data showing increased 1O2 levels correlate with specific manganese oxide interactions.
