Hydrogen generation in electrostatically stabilized, aqueous organic nanoparticle dispersions is investigated. For this purpose, organic nanoparticle dispersions are synthesized in water by nanoprecipitation from tetrahydrofuran and stabilized by charging through strong molecular electron acceptors. The dispersions are stable for more than 10 weeks on the shelf and during the photocatalytic process, despite the continuous transfer of charges between the reactants. The hydrogen generation in the electrostatically stabilized dispersions outperforms the hydrogen generation in organic nanoparticle dispersions which contain the common stabilizer sodium dodecyl sulfate.
研究了静电稳定的水性有机纳米颗粒分散体中的氢气生成。为此，通过从四氢呋喃中进行纳米沉淀在水中合成有机纳米颗粒分散体，并通过强分子电子受体充电来使其稳定。尽管反应物之间不断发生电荷转移，但这些分散体在货架上和光催化过程中可稳定超过10周。静电稳定分散体中的氢气生成性能优于含有常见稳定剂十二烷基硫酸钠的有机纳米颗粒分散体中的氢气生成性能。
