【名师讲座】龙德良：Unconventional types of polyoxometalates with unique electronic properties
名师讲座 龙德良 多金属氧酸盐
2023/6/20
多金属氧酸盐(POM)是一类前过渡金属元素簇状化合物，具有一系列非凡的物理化学性质，是功能非常有前途的纳米材。传统的多金属氧酸盐是由不具有氧化还原性的模板PO43-, SO42-, SiO42-等构建的。基于氧化还原活性模板(如SeO32-, TeO32-)的POMs更受关注，因为它们具有更多样化的结构类型和氧化还原活性，使它们具有进一步的应用潜力。在过去的二十年中，我们团队一直探索POM的前沿领...
