Table 2 in the original article shows the incorrect unit for the rate of NH₃ in two locations. The correct unit of the rate of NH₃ is 10⁻⁹ mol cm⁻² s⁻¹. Below is the correct version of Table 2.

Table 1 The parameters of the tested cells, including the current and voltage used for the NH₃ synthesis, the NH₃ synthesis rate (mol cm⁻² s⁻¹), energy consumption, the fraction of energy expended for NH₃ synthesis, the faradaic efficiency (Λ_F), and the energy efficiency (Λ_E)
