Impacting the Balance between CO 2 and Proton Reduction by Control over Aggregation in a Model π-Conjugated N‑Heterocycle – Proflavine

Puntos clave

• The aim is to understand how aggregation affects the selective photocatalytic reduction of CO2 compared to protons in proflavine.
• Investigated the aggregation behavior of proflavine under photocatalytic conditions
• Analyzed the selectivity of CO2 reduction versus proton reduction
• Used varying concentrations to assess the impact of dilution on catalytic performance.
• Under optimal diluted conditions, CO2 reduction was favored over proton reduction
• Aggregates formed at 65nm showed enhanced selectivity for CO2
• Mechanistic insights suggest specific factors of aggregation influence catalytic outcomes.
