年々、大気中の濃度が高まっていく二酸化炭素。2016年には濃度が400ppm(0.04%)を超えてしまった(図1)。 二酸化炭素には地球温暖化を促進する作用があるため、各国がさまざまな対策を進めている。2016年11月には「気候変動枠組条約第21回締約国会議」(COP21)で採択された新しい法的枠組み「パリ協定」が発効する見込みであり、二酸化炭素を中心とする温暖化ガス削減がいよいよ加速しそうだ。 対策の1つが二酸化炭素の再利用だ。自然エネルギーを利用して、植物のように大気中の二酸化炭素から有用な物質を合成できないだろうか。人工光合成が工業的に可能になれば化石燃料の消費量を減らすことができる。バイオマス燃料のように正味の二酸化炭素排出量の削減につながるからだ。 炭素原子1個から2個の利用へ 人工光合成には長い歴史があるものの、ここ数年で研究が大きく進んできた。現在は炭素原子1個を含む二酸化炭
