Chemical Immobilization of CO2 Through Molecular Manipulations of the Crossover and Interfaces between Molecular and Solid Catalyst

Outline of the Project

Changeover from our present way of thinking based on the chemical production from fossil resources to “producing materials from CO2 and returning to CO2” would be among the strongest request from the public society.  In this research, chemical manipulations of catalyst surfaces at the molecular level, namely, the fine-tuning of some common features, including the crossover and interfaces, across molecular catalyst and solid photo-catalyst, will be carried out for immobilizing CO2 as carbon resources.  The initial attempt will be made for the conversion of CO2 to MeOH promoted by molecular surface catalysts using heat energy and H2, with saving the energy input to the reaction.  Subsequent attempt includes the control of the diversity of hydrogen transfer processes occurring around the space nearby or in-between the two different catalyst surfaces (molecular surface and solid surface).  In the latter approach, light energy and H2O as the reducing agent will be used for the CO2 transformation.  Prospective results will have a ripple effect on the greener utilization of new chemical ingredient bases derived from CO2 and natural feedstock.  Tremendous technologies that should solve some environmental issues of the 21st century will show up in the future, based on the present pioneering concept “hydrogen management” as well as scientific significance.
