论文摘要
使用均质降水技术合成具有高形态规律性和亚微米侧尺寸的镍铁层双氢氧化物（Nife LDH）血小板，以高效地催化氧气进化反应（OER）。考虑到边缘位点是活动的点，为控制合成分散体内的血小板大小而努力。目的是可控制地隔离和表征尺寸减少的Nife LDH颗粒。基于与其他LDH材料的发表工作，我们无法转移Nife LDH血小板的尺寸控制的合成方法，因此，我们相反，我们使用合成后的治疗技术来提高边缘位点密度。最后，尺寸降低了Nife LDH/单壁碳纳米管（SWCNT）复合材料，可以进一步将OER ORPOTINECH降低至237 Plus/Minus 7 MV（L = 0.16 plus/sinus 0.01微米，20 wt％SWCNT），这是报告的最佳值之一。这种方法还改善了在工作条件下催化剂的长期活性。
Nickel-iron layered double hydroxide (NiFe LDH) platelets with high morphological regularity and sub-micrometre lateral dimensions were synthesized using a homogeneous precipitation technique for highly efficient catalysis of the oxygen evolution reaction (OER). Considering edge sites are the point of activity, efforts were made to control platelet size within the synthesized dispersions. The goal is to controllably isolate and characterize size-reduced NiFe LDH particles. Synthetic approaches for size control of NiFe LDH platelets have not been transferable based on published work with other LDH materials and for that reason, we instead use post-synthetic treatment techniques to improve edge-site density. In the end, size reduced NiFe LDH/single-wall carbon nanotube (SWCNT) composites allowed to further reduce the OER overpotential to 237 plus/minus 7 mV ( L = 0.16 plus/minus 0.01 micrometres, 20 wt% SWCNT), which is one of the best values reported to date. This approach as well improved the long term activity of the catalyst in operating conditions.
