Article Synopsis
- - The efficiency of lithium-sulfur batteries (LSBs) is hindered by poor anchoring materials, prompting research into two-dimensional MAZ monolayers for improved performance.
- - Density functional theory and machine learning techniques identify MoGeN and WGeN as the best candidates for anchoring materials due to their optimal adsorption energies for lithium polysulfides, which help reduce the shuttle effect.
- - The study also emphasizes the role of the electronegativity of element Z in MAZ, which significantly affects anchoring properties and can guide the design of high-performance LSBs in the future.
Compared to the traditional oxygen evolution reaction (OER), the urea oxidation reaction (UOR) generally exhibits a lower overpotential during the electrolytic process, which is conducive to the hydrogen evolution reaction (HER) at the cathode. The superior structure and abundant sites play a crucial role in promoting the adsorption and cleavage of urea molecules. Therefore, this paper introduces a simple metal cation-induced gelation method to prepare an electrocatalyst with PtNi alloy-NiO dual sites supported on TiCT, which simultaneously exhibits excellent UOR and HER performance.
