A nanostructured self-supported electrode Ce-CoFe-LDH/NF without adhesive was obtained directly, which has a regular nanoneedle morphology with a length of 1.2 渭m and tip width of 20 nm. Adopting Ce3+ ions with a large radius to partially displace Fe3+ ions with a small radius produced ...
Mn的引入改变了CoFe-LDH的电子结构,提高了其本征活性和电导率。此外,Mn/Fe比例的调节诱导了一种独特的纳米线-纳米片结构,提高了催化活性。与CoFe- LDH相比,当电流密度为100 mA cm−2时,CoFe0.75Mn0.25-LDH需要的过电位降低了32 mV...
Experiments show that the OER performance with 25%La-CoFe LDH and 25%Ce-CoFe LDH is better than CoFe LDH. And the oxygen evolution potential of 25%La-CoFe LDH at a current density of 10 mA/cm is 1.547 V, which is far lower than CoFe LDH(1.694 V). And it also has lower Tafel ...
