Comment on "MoS2/Ti3C2 heterostructure for efficient visible-light photocatalytic hydrogen generation"
In a recent article entitled "MoS2/Ti3C2 heterostructure for efficient visible-light photocatalytic hydrogen generation" published in this journal, MoS2/Ti3C2 heterostructure was prepared with excellent performance as photocatalyst for hydrogen evolution reaction. Although the materials were correctly made and tested, the presentation and explanation of X-ray diffraction (XRD) patterns are not correct. Some diffraction peaks are not indexed correctly. Therefore, better XRD patterns and explanation are suggested to ensure the reliability of the photocatalytic mechanism of MoS2/Ti3C2 in that paper. (C) 2020 Hydrogen Energy Publications LLC.
