Recently, Amir Razmjou has commented on “Tunable Nanoscale Interlayer of Graphene with Symmetrical Polyelectrolyte Multilayer Architecture for Lithium Extraction.” The author focused on the experimental results of the size of tunable nanoscale interlayer but completely ignored the value of the work. Based on the previous works of the phenomenon or theory of the appearance of morphological defects (cracks or pinholes) in graphene membrane, he provided his opinion that the selective separation of cations is due to the appearance of morphological defects (cracks or pinholes). Therefore, he made the conclusion that “the appearance of defects (cracks or pinholes) during bottom‐up synthesis of 2D nanochannels such as graphene oxide‐based membranes played important role in the selective transportation of Li+ ions.” Amir only focused on the interlayer spacing value of around 0.48 nm, which is an average value obtained by experimental measurements, and commented it based on the theories without any analysis of this work. However, he overlooked the theory and practice value of tunable nanoscale interlayer of graphene and many other evidences of this work.
