Interface-Enhanced Electrochemical Epoxidation Over a Core-Shell Nanozeolite TS-1@Mn-N-C Catalyst. [PDF]
Adv Sci (Weinh)Core–shell interface of TS‐1@Mn‐N‐C enables in situ generation of high‐concentration H2O2 and its spatially confined activation toward epoxidation‐active η‐Ti‐OOH species, leading to highly efficient and continuous electrochemical epoxidation. The work successfully addresses the key challenge of inefficient mass transfer and slow kinetics caused by ...

ROLE OF Mn(TPP)Cl IN THE EPOXIDATION WITH SINGLET OXYGEN [PDF]
Journal of Sciences, Islamic Republic of Iran, 2000 Mn(TPP)Cl catalyzes cooxidation of olefin in the singlet oxygenation of sulfid. Mn(TPP)Cl is able to transfer an oxygen atom from a peroxidic intermediate generated in singlet oxygenation of sulfide to a metal ion affording metal 0x0 species which is ...
