Innovation of New Energy Resources and Foundation of New Social Systems

All across the world, people are facing energy problems on a global scale. As part of a paradigm shift on energy resources, development of new energy resources such as artificial photosynthesis has been investigated to escape from the present situation that mainly depends on fossil fuels. One practical way to solve this problem is to use renewable energy such as sunlight, wind power, tidal power, geothermal power and so forth.

However, conversion of energy into high energy materials leading to new energy resources widely available in society is necessary to use renewable energy efficiently.

Our laboratory is challenging the generation of new energy resources and an innovative social system using it.

Development of New Catalysis Technology to Convert Ammonia into Resources

Ammonia has been synthesized from the atmospheric dinitrogen and is now expected as a new energy resource that emits only water and dinitrogen.

We are developing next-generation nitrogen fixation catalytic system necessary to realize "ammonia society" where ammonia is used as an energy resource. We have designed several dinitrogen complexes that can work as molecular catalysts to convert dinitrogen into ammonia under mild reaction conditions.

Development of Novel Catalyses as Solutions to Shortage of Energy Resources

Plastic and chemical products such as pharmaceuticals around ours are synthesized by accumulation of chemical reactions using catalyst. The development of more efficient synthesis method is important from the viewpoint of resources and energy. Chemical products such as plastics and pharmaceuticals are synthesized by several chemical reactions. Thus, development of more efficient synthetic methods is important to solve the shortage of energy resources. Our group is working on the development of novel and practical chemical reactions for the future.
