Novel physical properties of nanohybrid materials between polynuclear metal complexes and nanocarbons

多核金属络合物、分子簇具有10个以上的电子氧化还原能力，有望成为下一代电子存储材料。在本工作中，我们制备了多金属氧酸盐(POM)分子簇与石墨烯、介孔碳等纳米碳化物之间的纳米杂化材料，并对其电池性能进行了详细的研究。结果是，由于POM的超还原和纳米碳的双电层电容的组合，通过纳米杂化增强，获得了极大的容量。此外，我们还开发了一套现场电化学-磁测量系统，并将其应用于磁性团簇。然后，我们成功地连续改变了磁体的转变温度和矫顽力等磁性，这为电化学磁体开辟了一条新的途径。

Poly-nuclear metal complexes, molecular clusters, are promising as next-generation electron storage materials since they exhibit more than ten electrons redox. In this work, we developed nanohybrid materials between one of molecular clusters, polyoxometalate (POM), and nanocarbons such as graphene and mesoporous carbon, and then their battery performances were investigated in details. As a result, extremely large capacities were obtained due to a combination of a super-reduction of POM and electrical double layer capacitances of nanocarbons which are enhanced by nanohybridization. Additionally, we also developed an in situ electrochemistry-magnetic measurement system and applied it to magnetic clusters. Then, we succeeded in changing magnetic properties such as transition temperatures and coercivities continuously, which opens an avenue to electrochemical magnets.
