摘要

由单一有机半导体形成的光催化剂通常具有低效的本征电荷产生,这导致光催化活性低。我们证明了在有机纳米颗粒(NPs)中加入供体聚合物(PTB7-Th)和非富勒烯受体(EH-IDTBR)之间的异质结可以导致析氢光催化剂的光催化活性大大增强。通过改变NP制造过程中使用的稳定表面活性剂,将其从核壳结构转变为混合的供体/受体混合物,并将H2的演化增加一个数量级,可以实现这些NP的纳米形态控制。所制备的光催化剂在350 ~ 800 nm光照下表现出前所未有的高氢气析出率,超过60,000µmol h-1 g-1,在最大太阳光子通量区域外量子效率超过6%。

Enhanced photocatalytic hydrogen evolution from organic semiconductor heterojunction nanoparticles

Enhanced photocatalytic hydrogen evolution from organic semiconductor heterojunction nanoparticles
Photocatalysts formed from a single organic semiconductor typically suffer from inefficient intrinsic charge generation, which leads to low photocatalytic activities. We demonstrate that incorporating a heterojunction between a donor polymer (PTB7-Th) and non-fullerene acceptor (EH-IDTBR) in organic nanoparticles (NPs) can result in hydrogen evolution photocatalysts with greatly enhanced photocatalytic activity. Control of the nanomorphology of these NPs was achieved by varying the stabilizing surfactant employed during NP fabrication, converting it from a core–shell structure to an intermixed donor/acceptor blend and increasing H2 evolution by an order of magnitude. The resulting photocatalysts display an unprecedentedly high H2 evolution rate of over 60,000 µmol h−1 g−1 under 350 to 800 nm illumination, and external quantum efficiencies over 6% in the region of maximum solar photon flux. Photocatalysts formed from a single organic semiconductor can suffer from inefficient charge generation leading to low photocatalytic activities. Incorporating a heterojunction between a donor polymer and non-fullerene acceptor in organic nanoparticles leads to enhanced photocatalytic hydrogen evolution.
