Density generalized function theory
WebDensity-functional theory with generalized gradient approximation for the exchange-correlation potential has been used to calculate the global equilibrium geometries and electronic structure of neutral, cationic, and anionic … WebDensity functional theory (DFT) calculations are based on quantum mechanics, which can calculate the electronic structure of the whole catalytic system. It is probably the most powerful computational approach to investigate the structure–activity relationships of electrocatalysts at atomic level.
