Abstract
The photoelectrochemistry at semiconductor electrodes has been used to design systems for heterogeneous photosynthesis1–7 and photocatalysis8–10. There has been, however, no attempt at the organic synthesis of highly valuable compounds from cheap raw material except for a very low yield of amino acids11 produced from methane–ammonia–water. If such products were to be formed in one step by heterogeneous photocatalytic reactions, this would be a highly efficient means for the economical utilization of solar energy in comparison with hydrogen production, even though the reactions are driven in a spontaneous (ΔG°<0) direction by the light energy.
