Isotopic Studies of Heterogeneous Catalysis (Ozaki, Atsumu)

Model studies in heterogeneous catalysis.

I review a concept that models heterogeneous catalysis based on a surface-science approach. It is shown that models catching part of the complexity of the real system, which is connected with the finite size of active components and the flexibility of the arrangement of atoms in the active component, play an important part in determining the activity and selectivity of the system. I have chosen...

Heterogeneous asymmetric catalysis*

Examples of enantioselective catalysts, including homogeneous supported catalysts and biphasic liquid/liquid, are described and compared. In the case of asymmetric hydride transfer, polythiourea was proven to be more efficient for ruthenium-catalyzed reduction of aryl ketones, although the iridium complexes gave rise to higher ee when using amino sulfonamide bound to a polystyrene matrix. In th...

Heterogeneous Catalysis for Environmental Remediation

The intensive human activities in chemical industry and environmental purification urge the development of advanced protocols for green production and waste management. In environmental science, developing highly efficient and environmentally-friendly catalytic materials and systems are very favourable approaches to green chemical synthesis and remediation of contaminated air, soil, and wastewa...

Heterogeneous Catalysis for Tandem Reactions

As long as the molecular complexity increases, the number of chemical transformations will increase in parallel, becoming a highly demanding synthetic process in terms of time and resources. Since the loss of material after each purification step will also dramatically reduce the overall efficiency of a synthetic process, the conversion of such transformation into a practical and efficient proc...
