Description
発明は、二酸化炭素の還元のための電極に関し、より特定的には、二酸化炭素の還元のための、自己組織化単分子膜がその上に付いた電極に関する。
化石燃料は、燃料源またはさまざまな製品のための供給原料などのさまざまな機能に利用される限りのある資源である。化石燃料の燃焼は環境中のCO2の量を増大させる。電解セルを水媒体中でのCO2の電気化学的還元に利用して、H2、CO、アルコール、蟻酸、メタン、および短鎖アルカンなどのさまざまな生成物を産生し得る。これらの生成物のうち、H2とCOとの混合物(合成ガス)が非常に望ましい。なぜなら、それは液体炭化水素の生産のための商用フィッシャー−トロプシュ法への供給原料として働くことができるからである。制御された比率でH2およびCOを選択的に産生することはフィッシャー−トロプシュ法に有益であろう。
1つの局面では、一酸化炭素と水素とを形成する水および二酸化炭素の電気化学的還元のための電極が開示される。電極は金属基板を含む。自己組織化単分子膜が金属基板に結合される。電極によって産生される一酸化炭素と水素との反応生成物の選択性は剥き出しの金属基板に対して調節される。
図1を参照して、一酸化炭素と水素とを形成する水および二酸化炭素の電気化学的還元のための電極10の図が示される。電極は金属基板15を含む。自己組織化単分子膜20が金属基板15に結合される。
金属基板15は、一酸化炭素の結合強さが低い金属から形成され得る。1つの局面では、結合強さは、CO吸着エネルギが1eV未満であることを特徴とし得る。1つの局面では、金属は、Au、Ag、Zn、Pd、およびGaから選択され得る。
