| Abstract |
Mesoporously restacked nanocomposites of layered double hydroxide (LDH)-transition metal oxide (TMO) are synthesized by electrostatically-driven self-assembly of cationic exfoliated LDH nanosheets and anionic exfoliated TMO nanosheets. The obtained LDH-TMO nanocomposites show outstanding electrocatalytic activities for oxygen evolution and oxygen reduction. Of noteworthy is that the hybridization of LDH with TMO is quite effective in improving its chemical stability. The beneficial effect of TMO incorporation on the electrocatalyst performance is ascribable to the increase of electrical conductivity and the provision of more surface active sites of LDH material. The present study clearly demonstrates that the incorporation of TMO nanaosheets can provide a facil and efficient method to explore high performance bifunctional electrocatalyst materials as well as efficient catalysts for Li-O2 batteries. |
