Correction to “Activating the Microsized Cubic Co ₃ O ₄  with Doping Y ₂ O ₃  Phase Inlaid on the Plasma‐Treated Soft Carbon Fiber for a Robust Electrocatalytic Alkalized‐Seawater Splitting”

2.2 Some information was missing from section 4 Figure 5 was inconsistent with the standards of published AEMWE figures 2.2.Electrocatalytic Performance of the Catalysts An earlier explanation of the testing area of AEMWE showed a writing error, and the testing area should be 1 1 cm 2 , not 2 2 cm 2 .The corrected presentation should be "As illustrated in Figure 5a, the AEMWE device utilizes Y 2 O 3 -Co 3 O 4 /PCC as both the anode (+) and cathode (-) electrodes, which have an equal surface area of 1 1 cm 2 " 4. Experimental Section Electrochemical measurement: the information of the current amplifier (model: CHI 680D) was not provided in the original article.The corrected contents should be "All electrochemical tests of the catalysts were conducted at room temperature in 1.0 M KOH (pH 14) or 1 M KOH + seawater (pH 14) using an electrochemical workstation (model: CHI 660E, as well as equipped with a current amplifier (CHI680D), Shanghai Chenhua Instrument Co., Ltd.), which followed similar processes as reported in our former works.[59-61]"Finally, most of the spectra curves of Figure 5 were drawn by the separated dots.In particular, the current density was negative data, which was based on the raw data.However, this is inconsistent with many published AEMWE figures, which caused some confusion.Therefore, we replace the former Figure 5 with the new figure.
