虽然这些实验过程给我们提供了试错经验,微语但是失败的实验数据摆放在那里彷佛变得并无用处。
2018年,录精斯坦福大学鲍哲南课题组发现了一类性质稳定、合成方法简单的导电MOF:Cu-HAB[5],Co-HAB[6],在电容器和电池方面具有优异的性能。其电导率为6×10-4 Scm-1(300K),神仙热活化能为0.193eV。
不食Talin[10]等人证明了将具有氧化还原活性的共轭分子作为客体分子渗透到MOFs骨架中能够产生有效的电子传导途径。短短十年间,人间更准确地说是短短五年间,人间各顶刊中不断出现导电MOF的成果,导电MOF迎来了爆发式的发展,无疑是材料界一颗冉冉升起的新星,如果你也喜欢在新领域里做开拓者,那导电MOF将是一个极佳的课题,值得探索。I2的掺杂量很小,烟火表明是通过框架而不是通过I2客体分子发生了导电行为。
微语相对较高的ZT值归因于室温下的低热导率(0.27Wm-1 K-1)和超高塞贝克系数(375 μVK-1)。除HER外,录精导电MOF在催化OER方面也很有前景。
