Descripción

Application

• Investigations of the reaction mechanism of sodium with hydrogen fluoride to form sodium fluoride and the adsorption of hydrogen fluoride on sodium fluoride monomer and tetramer.: This paper delves into the reaction mechanisms between sodium and hydrogen fluoride, and the adsorption properties on sodium fluoride structures. These findings are essential for chemists working on chemical synthesis, reaction kinetics, and industrial applications of fluoride compounds (Yu et al., 2024).
