Enhanced photocatalytic hydrogen evolution from organic semiconductor heterojunction nanoparticles
Open accessAbstract
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 H 2 evolution by an order of magnitude. The resulting photocatalysts display an unprecedentedly high H 2 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.

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
