Ni<sub>3</sub>S<sub>2</sub>/M<sub><i>x</i></sub>S<sub><i>y</i></sub>–NiCo LDH (M = Cu, Fe, V, Ce, Bi) heterostructure nanosheet arrays on Ni foam as high-efficiency electrocatalyst for electrocatalytic overall water splitting and urea splitting

Abstract
at 1.56 V with outstanding durability for overall urea splitting, which is better than that of the overall water splitting. Density functional theory (DFT) calculation shows that the superior electrocatalytic activity can be explained by the water adsorption energy being optimized and enhanced conductivity. This study provides a new idea for improving the catalytic activity and stability of non-noble metals instead of noble metals.
