Surface| Резюме: | The equilibrium spatial structures and formation energies have been calculated for sulfuric acid complexes on silica surface by means of ab initio Hartree-Fock-Roothaan method with use of extended basis set 6-31G**. The interaction has been examined between orthosilicic acid and sulfuric acid molecules accompanied by three water molecules. The energy effects have been calculated for destruction of disulfuric acid molecules due to the interaction with orthosilicic acid molecules as well for siloxane bond cleavage of a disilicic acid molecule due to interaction with a disulfuric acid molecule |
