Ultrafine, highly dispersed Pt clusters were immobilized onto the Co nanoparticle surfaces by one-step pyrolysis of the precursor Pt(Ⅱ)-encapsulating Co-MOF-74. Owing to the small size effects of Pt clusters as well as the strongly enhanced synergistic interactions between Pt and Co atoms, the obtained Pt-on-Co/C400 catalysts exhibited excellent catalytic activity toward the hydrolysis of ammonia borane with an extremely high turnover frequency (TOF) value of 3 022 min^-1 at 303 K. Durability test indicated that the obtained Pt-on-Co/C400 catalysts possessed high catalytic stability, and there were no changes in the catalyst structures and catalytic activities after 10 cycles.

中国科学技术大学化学国家级实验教学中心所开设的“仪器分析实验”为安徽省课程思政示范课程，在实验项目“气质联用法测定饮料中塑化剂含量”的教学过程中，课程组针对课程的特点和教学过程，对该项目进行思政示范教学案例设计。思政案例库的建设，有助于教师充分挖掘专业课程中的德育元素，激发学生的学习兴趣，培养学生的自主创新意识，取得了良好的教学效果。
