| Outline of Final Research Achievements |
A multi-functional hybrid catalyst composed of aminopolymer with CO2 adsorption property, Ir-phosphine complex with CO2 hydrogenation ability and titanate nanotube as a support was developed in order to realize efficient production of formic acid from CO2. Immobilization of poly(ethyleneimine)-tethered Ir-iminophosphine complex into the cavity space of titanate nanotube led to a remarkable improvement of catalytic activity and reusability. Comprehensive analyses of active centers and its structural change during the catalysis by various spectroscopic measurements revealed the reaction mechanism, and the synergism between the functionalities was investigated.
