the development of energy storage mechanisms. The hydrogenation of CO2 into formic acid or methanol could function as a means to store energy in a chemical bond. The catalyst reported here operates under low pressure, at room temperature, and in the presence of a base much milder (7 pKa units lower) than the previously reported CO2 hydrogenation catalyst, Co(dmpe)2H. The Co(I) tetraphosphine complex,
大规模实施碳中和能源(例如太阳能和风能)将需要发展储能机制。将CO 2加氢成甲酸或甲醇可以用作以化学键存储能量的手段。此处报道的催化剂在低压,室温下和比以前报道的CO 2加氢催化剂Co(dmpe)2 H弱得多的碱(低7 p K a单位)的条件下运行。 )四膦配合物[Co(L3)(CH 3 CN)] BF 4,其中L3 = 1,5-二苯基-3,7-双(二苯基膦基)丙基-1,5-二氮杂-3,7-二磷环辛烷(0.31 mM),催化CO 2于25°C时以150(20)h –1的初始转换频率,1.7 atm的H 2和CO 2 1:1混合物以及0.6 M 2-叔丁基-1,1,3,3进行氢化-四甲基胍。
