摘要：为提升学生综合能力,培养创新型人才,在基础化学实验教学中引入了项目制研究性学习法。将知识面宽、应用性广、前沿性强的科研课题“胶体金纳米颗粒的制备及应用”打造为创新探索性实验项目。以科研项目为牵引,以问题为导向,以综合能力培养为目标,引导学生进行主动学习、团队协作、自主设计探究,不断提升自身能力素养。在实验教学过程中不断迭代改进教学方法,创设更加开放、自主的实验环境,完善多维性评价体系,总结项目制研究性学习法的应用要点及注意事项,最终为基础化学实验课程提供了一种培养本科生创新思维和科研能力的教学模式。

摘要：The activation of HCl by cationic Au in the presence of C2H2 is important for the construction of active Au sites and in acetylene ***,we report a strategy for activating HCl by the Au-based supported ionic liquid phase(Au–SILP)technology with the[N(CN)2^–]*** strategy enables HCl to accept electrons from[N(CN)2^–]anions in Au–[N(CN)2^–]complexes rather than from pure[Bmim][N(CN)2],leading to notable improvement in both the reaction path and the stability of the catalyst without changing the reaction triggered by acetylene ***,the induction period of the Au–SILP catalyst was shown to be absent in the reaction process due to the high Au(III)content in the Au(Ⅲ)/Au(Ⅰ)site and the high substrate diffusion rate in the ionic liquid *** work provides a facile method to improve the stability of Au-based catalysts for acetylene hydrochlorination.
