摘要：

Herein, we investigated the role of Pt metal cocatalyst and hydroxyl additives in the mechanism and activity of hydrogen evolution over the PCBM/PF3T organic nanohybrid. We show, for the first time, the addition of hydroxyl additives to improve the HER performance of the system, recording up to 70 mmol g(-1) h(-1) (AQY = 2.0%), which is among the best for an organic HER photocatalyst. The enhanced activity is explained by the binding of hydroxyl additives to Pt, funneling proton adsorption onto the Pt sites where more efficient H-2 formation occurs thereafter. These insights will be critical for future organic photocatalyst designs.
