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.

基于向大一学生开设的“电解-量气法测定阿伏加德罗常数”实验，设计了Cu₂O的电化学合成及量气法测定阿伏加德罗常数一体化实验，该实验巧妙地融合了元素化学实验中有关Cu₂O的制备及性质实验内容。一次电解完成两个实验，节约电能，节省时间。Cu₂O的电化学合成及量气法测定阿伏加德罗常数一体化实验可作为一个微实验灵活穿插于大学基础化学实验教学中，对于培养大一学生的全方位思考的意识和多角度分析问题的能力以及经济、环保的理念有重要意义。
