Electron Hopping Process in SWCNT-Mediated Redox Reaction: An Evidence Observed by DFT Theory

Nongnual T., Choomwattana S., Nokbin S., Khongpracha P., Limtrakul J., Laboratory for Computational and Applied Chemistry, Physical Chemistry Division, TH

The electron hopping in SWCNT-mediated redox reaction of anthraquinonnyl (AQH2-) and 4-arylhydroxyl amine (4AHA-) groups is systematically studied by DFT for the first time. The spin-unrestricted DFT calculations were performed with generalized gradient approximation (GGA) [...]

The Theoretical Investigation of Oxidative Dehydrogenation of Ethane to Ethene over Fe-ZSM-5: a QM/MM Study

Bobuatong K., Sirijaraensre J., Khongpracha P., Pantu P., Limtrakul J., Laboratory for Computational and Applied Chemistry, Physical Chemistry Division, TH

The complete detailed reaction mechanism for the oxidative dehydrogenation of ethane over Fe-ZSM-5 zeolite has been systematically investigated by means of the ONIOM(MP2/6-31G(d,p):UFF)//ONIOM(B3LYP/6-31G(d,p):UFF) scheme. Two types of reaction mechanisms for the oxidative dehydrogenation of ethane [...]

Dehydration of Hydrous Ethanol to Ethylene over H-MOR Investigated by the ONIOM Method

Meeprasert J., Choomwattana S., Pantu P., Limtrakul J., Laboratory for Computational and Applied Chemistry, Physical Chemistry Division, TH

The conversion of ethanol to ethylene, which is one of the most important feed stocks for the petrochemical industry, is of particular commercial interest. Two mechanisms, stepwise and concerted, of the ethanol dehydration to ethylene [...]
