The method comprises:(1) weighing lead acetate hexahydrate and thioacetamide, and preparing aqueous solutions respectively, so that the concentration ratio of Pd2+ to S is 1:(1-4);(2) adding acetic acid into thioacetamide solution to adjust the pH value to 2-4;(3) adding poly surfactant into lead acetate solution, ultrasonicating to mix uniformly and obtain a colorless and transparent sol;(4) mixing the sol and thioacetamide solution;(5) placing the mixed solution in a sealed container, irradiating by 2.5 MeV and 40 mA electron accelerator with irradiation dose of 25-40 Mrad;(6) washing the product, centrifuging for separation, and drying to obtain black PdS nanoparticles.

本发明方法的工艺过程如下：首先称取一定量的六水合醋酸铅和硫代乙酰胺，各自配制成水溶液，其浓度比为使其中的铅离子浓度与硫原子浓度的比例为1∶1～1∶4；在硫代乙酰胺溶液中加入适量醋酸调节其pH值至2～4；醋酸铅溶液中加入少量表面活性剂聚乙烯醇，然后超声振荡，混合均匀，制成无色透明溶胶；随后将溶胶与上述的硫代乙酰胺溶液混合；将该混合液置于密闭容器中，并将其放置于2.5MeV、40mA的电子加速器产生的电子束辐照下进行辐照处理，其辐照剂量为25～40Mrad；然后将反应生成物清洗，并用高速离心机离心分离，然后干燥，最终得到黑色纳米硫化铅颗粒。
