WebNov 8, 2024 · Additionally, by analyzing the partial density of states and projected crystal orbital Hamilton population, the anti-bonding states become less occupied and the adsorption strength of OH is enhanced in 2Mn–C 3 N 4. Web12 hours ago · Moreover, we revealed the origin of the electrocatalytic activity using the crystal orbital Hamilton population (COHP) and the molecular orbitals (MOs). Our results provide a strategy for the design of novel synergistic trifunctional electrocatalyst for HER/OER/ORR, and this approach can be applied to other carbon-based nano-materials. 2.
