要旨

The selective reductive amination of carbonyl compounds is efficiently promoted using titanium oxide uniformly doped with carbon (TiOx–C), either as a photocatalyst or thermocatalyst. For the reductive amination of 3-phenylpropanal, 82.7% conversion of 3-phenylpropanal and 99.0% selectivity of N,N-dimethyl-3-phenylpropan-1-amine was achieved using TiOx–C as a photocatalyst at room temperature under visible light irradiation. In addition, 98.9% conversion with 99.0% product selectivity was attained at 90 °C under no light when TiOx–C was employed as a thermocatalyst. Therein, the efficient separation of photogenerated electron and holes of TiOx–C is the key factor during the photocatalytic process; while, the acidic sites of the surface and oxygen vacancies of TiOx–C are responsible for its high efficiency in the thermocatalytic reductive amination reaction.

Reaction Chemistry & Engineering is an interdisciplinary journal reporting cutting-edge research focused on enhancing the understanding and efficiency of reactions. Reaction engineering leverages the interface where fundamental molecular chemistry meets chemical engineering and technology. Challenges in chemistry can be overcome by the application of new technologies, while engineers may find improved solutions for process development from the latest developments in reaction chemistry. Reaction Chemistry & Engineering is a unique forum for researchers whose interests span the broad areas of chemical engineering and chemical sciences to come together in solving problems of importance to wider society. All papers should be written to be approachable by readers across the engineering and chemical sciences. Papers that consider multiple scales, from the laboratory up to and including plant scale, are particularly encouraged.
