Description
[0001] 本発明は、海軍研究局学際的大学研究イニシアチブによって授与された助成金N00014−11−1−0725、及び空軍科学研究局によって授与された助成金FA9550−09−1−0689の下で政府の支援でなされた。政府は本発明において一定の権利を有する。
[0025] 実験に使用した反応器は、水素発生反応(HER)のためのコバルト−リン(Co−P)合金陰極及び酸素発生反応(OER)のためのリン酸コバルト(CoPi)陽極を含む生体適合性水分解触媒システムを含んでいた。このシステムは、アンモニアを生成するのに使用する所望の水素を生成しながら、低駆動電圧(Eappl)の使用を可能にした。具体的には、N2及びH2OからのNH3合成は、水分解システムを使用し、H2酸化型独立栄養微生物内でN2還元反応を促進することで達成された。この場合、キサントバクター・オートロフィカス(X.オートロフィカス)を使用した。X.オートロフィカスは、ジアゾトロフの小グループに属するグラム陰性菌であり、これは微好気性条件(O2約5%未満)でH2をそれらの唯一のエネルギー源として使用してCO2とN2をバイオマスに固定することができる。したがって、この実験的設定では、電気化学的水分解は、生物学的エネルギー源としてH2を生成し、同じ反応器内で、X.オートロフィカスは、室温のN2還元反応触媒として作用して、H2及びN2をNH3に変換した。
