英文摘要	We have obtained new evidence, 6 years after the publication of our Report “Ammonia synthesis by N2 and steam electrolysis in molten hydroxide suspensions of nanoscale Fe2O3” ([ 1 ][1]), that there is a trace NOx− impurity in the nanoscale Fe2O3 that was unknown at the time. We no longer have the original nanoscale Fe2O3, and manufacturers' content levels of impurities in chemicals may vary over time. However, recently purchased nanoscale Fe2O3 per gram contains 0.0005 g N as NOx−, and an 15N2 isotopic tracer analysis conducted by Wenzhen Li, Yifu Chen, and Hengzhou Liu at Iowa State University; Shuang Gu at Wichita State University; and author S.L. suggests that this trace impurity, rather than N2, is the major nitrogen reactant in the observed ammonia synthesis. We are retracting the original Report, and we encourage exploration of an N2 to NOx− intermediate to ammonia pathway, rather than direct elemental nitrogen pathway, to ammonia synthesis. All observed stimulation of ammonia generation with these (likely NOx−-containing) nanoscale Fe2O3 materials, as well as all thermodynamic calculation results, remain accurate as documented in the original Report. 1.
