Photocatalytic ethane conversion on rutile TiO₂(110): identifying the role of the ethyl radical.

ABSTRACT: Oxidative dehydrogenation of ethane (C₂H₆, ODHE) is a promising approach to producing ethene (C₂H₄) in the chemical industry. However, the ODHE needs to be operated at a high temperature, and realizing the ODHE under mild conditions is still a big challenge. Herein, using photocatalytic ODHE to obtain C₂H₄ has been achieved successfully on a model rutile(R)-TiO₂(110) surface with high selectivity. Initially, the C₂H₆ reacts with hole trapped O_Ti^- centers to produce ethyl radicals , which can be precisely detected by a sensitive TOF method, and then the majority of the radicals spontaneously dehydrogenate into C₂H₄ without another photo-generated hol
