Abstract

The controlled nucleation and crystallization of small pure sphalerite ZnS nanoparticles was achieved under batch and continuous flow conditions at low temperature, in water and without the use of any stabilizing ligand. The obtained nanoparticles displayed a narrow size distribution and high specific surface area. Moreover, the synthesis was suitable to directly obtain stable water-based suspensions and the products were found to be active photocatalysts for the hydrogen evolution reaction.

摘要

在低温下，于水相中且不使用任何稳定配体的情况下，通过间歇式和连续流动条件实现了小尺寸纯闪锌矿型硫化锌（ZnS）纳米颗粒的可控成核与结晶。所获得的纳米颗粒呈现出窄尺寸分布和高比表面积。此外，该合成方法适合直接获得稳定的水基悬浮液，并且发现产物是用于析氢反应的活性光催化剂。
