摘　　要：采用胶体化学法,以氧化钨(W_(18)O_(49))为钨源制备出花状硒化钨纳米晶。采用透射电子显微镜(TEM)、高分辨透射电镜(HRTEM)和X射线衍射(XRD)手段对硒化钨纳米晶进行表征。本文对硒化钨花状纳米晶体的可控合成进行了初步探索,同时对烧结后的硒化钨纳米晶进行了电催化产氢测试。结果表明,硒化钨花状纳米晶具有良好的电催化性能。Floriated WSe2 nanocrystals were prepared by colloid chemical method using W180 49 nanowires as tungsten source. WSe2 nanocrystals were characterized by transmission electron microscopy （ TEM）, high resolution transmission electron microscopy （HRTEM） and X-ray diffraction （ XRD）. The controlled growth of the floriated WSe2 nanocrystals are preliminary explored in this article. After sintered, the electric catalytic hydrogen evolution performance of WSe2 nanocrystals were tested. The experimental results show that the floriated WSe2 nanocrystal has good catalytic performance.
