Here, Fe, Co-layered double hydroxide and polyaniline composites onto nickel foam (NF) (FeCo-LDH/PANI) were fabricated via one-step co-electrodeposition method. The test results indicate the co-existence of the amorphous structure and the smaller size of crystal district with more defects in ...
Interface engineeringWater-splittingDFTDeveloping efficient and inexpensive OER electrocatalysts is a challenge for overall water splitting.Herein,the heterostructured Fe Co LDH@NiCoP/NF nanowire arrays with high performance were rationally designed and prepared using an interface engineering strategy.Benefit...
Recent researches have shown that layered double hydroxides (LDH) are promising candidates towards OER, but further improvement is still highly demanded for its large-scale practical application in water splitting. Herein, we report a 3D P-doped MoO3/FeCo LDH/NF (P–MoO3/FeCo LDH/NF) ultra...
Initially, FeCo Lyared Double Hydroxides (FeCo LDH) nanosheets were realized via the hydrothermal technique. These sheets' precursors were further converted into FeCO2O4 nanosheets by annealing. The FeCo LDH sheet's structure was converted into FeCo2S4 nanorods by a one-step sulfidation process. ...
