The transformation of CO₂ into chemical feedstocks or fuels is an attractive goal, but catalysts capable of generating useful, multicarbon products have been challenging to design. Here, thin films of the intermetallic Ni₃Al on glassy carbon are found to be electrocatalytic for aqueous CO₂ reduction. At–1.38 V vs Ag/AgCl, Ni₃Al films produce a range of C1, C2, and C3 oxygenated organic species including 1-propanol and methanol at Faradaic efficiencies that are competitive with single-metal electrodes reported in the literature. To the best of our knowledge, Ni₃Al on glassy carbon is the only noncopper-containing material shown to generate C3 products.

玻碳电极上的Ni-Al膜从CO ₂生成一系列氧化有机物

将CO ₂转化为化学原料或燃料是一个有吸引力的目标，但是能够产生有用的多碳产物的催化剂的设计一直面临挑战。在此，发现玻璃态碳上的金属间化合物Ni ₃ Al的薄膜可电催化CO ₂水溶液的还原。在相对于Ag / AgCl为1.38 V时，Ni ₃ Al膜以法拉第效率产生了一系列的C1，C2和C3含氧有机物，包括1-丙醇和甲醇，与文献中报道的单金属电极竞争。据我们所知，玻璃碳上的Ni ₃ Al是唯一显示出可生成C3产物的不含铜的材料。
