| Abstract |
The efficient electrochemical conversion of CO2 to fuels or stock chemicals with high-energy density would be a major step forward in the introduction of a carbon neutral energy cycle, as it would allow for the direct low-temperature conversion of photo-generated electrical current to stored chemical energy, in a manner very similar to the way nature stores solar energy. The high activity and selectivity towards electrocatalytic conversion of CO2 can be achieved with careful selection of catalyst and electrolyte.
In addition, ammonia (NH3) synthesis, mainly for fertilizers, from N2 has been performed via the Haber-Bosch process at high temperature and pressure, consuming large amount of H2 from fossil resources and more than 1% of the total fossil energy consumption on Earth. Instead, the development of an efficient electrochemical process to generate carbon-neutral NH3 under ambient conditions using renewable energy sources becomes essential.
In this talk, recent attempts for efficient electrosynthesis of value-added chemicals will be introduced.
