该文章首先利用电化学沉积法在泡沫镍表面沉积一层聚苯胺,再通过水热法在其表面生长MOF-74-Co/Fe纳米棒阵列,最后通过氮气气氛下热解一步法得到CoFe2O4/C多孔的复合纳米棒阵列,避免了二次空气处理时碳材料的消耗及结构的破坏。泡沫镍表面沉积的聚苯胺对捕获过渡金属离子及诱导晶体生长取向起到了重要的作用。这种热解...
(3)将混合液b转至油浴锅中,随后缓慢将a溶液加入到b溶液中,在100℃反应时间为2h,用超纯水和无水乙醇洗涤,然后冷冻干燥24h,得到黑色沉淀物(双金属co3.4/fe0.6-mof-74金属有机骨架材料); (4)将得到的黑色沉淀物置于刚玉瓷舟中,在氩气气氛下热处理,热处理温度为800℃,升温速率为3℃/min,保温时间为3h,得到co...
进一步在氮气气氛下热解CoFe-MOF/C3N4,最终得到CoFe@NC/NCHNSs。在这一策略中,H2bpydc由于具有丰富的官能团,不仅能够作为链条稳定作为CoFe合金,还可以作为转化成氮掺杂碳壳保护合金,避免合金腐蚀和流失。薄层C3N4纳米片可以作为牺牲模板和氮源,有利于控制CoFe合金的尺寸,防止热解过程中CoFe合金颗粒的团聚。材料表征▲图2...

虽然采用双金属MOFs被用作前驱体来制备金属氧化物已有尝试,但由于不同金属离子与有机配体间的化学配位行为存在显著差异,使得对于不同金属位点的组成和结构的控制变得很难。为了克服这些问题,该研究团队通过交换配位-热解法完成了将有机金属化合物(C4H6CoO4)封装的FeBTC转化为尖晶石CoFe2O4/C纳米立方体。与无机Co2+...
