Erratum: Designing a Fe^III-doped nickel sulfide/carbon nanotube hybrid catalyst for alkaline electrolyte membrane water electrolyzers and Zn-Air battery performances (ACS Applied Energy Materials (2020) 3:11 (10961-10975) DOI: 10.1021/acsaem.0c01931)

The authors regret that the original Supporting Information (SI) document contains errors and is incorrect. It should be replaced with the new, corrected SI file. In the revised Supporting Information, we have changed the sentences about the gas chromatography (GC) setup used for water electrolyzer experiments as follows (section Materials and Methods in Section 1.1): The gas chromatography (GC) setup used for water electrolyzer experiments is a Micro GC 3000A model of Agilent (we thank Prof. Hirosige Matsumoto, I2CNER, Kyushu University for the use of this machine). The electrochemical cell for attenuated total reflectance infrared (ATR-IR) of the VeeMax III model was purchased from Pike Technologies. In these experiments, we used a ZnSe crystal of 60° reflection angle for all measurements. The electrochemical cell for FT-IR was constructed by ourselves. The peristaltic pump was used from mini-pump variable flow of Fisher brand.
