Abstract：Facing the major national strategies of “carbon peak” and “carbon neutralization”， hydrogen energy， as a green energy with high energy density and no pollution， will become the top priority in the future development of energy strategy in China and even the world. Hydrogen production from electrolytic water has attracted much attention because of its simple preparation method， high hydrogen purity and no pollution in the preparation process. However， this method has a serious defect， that is， the lack of low-cost and high efficiency hydrogen evolution reaction catalyst. MXenes is a new two-dimensional (2D) transition metal carbide， nitride and carbon nitride. Because of its excellent conductivity， good hydrophilicity， huge specific surface area， adjustable molecular structure and diverse chemical composition， MXenes has potential applications in the field of hydrogen evolution catalysts. This paper summarizes the preparation of MXenes， the performance regulation strategy of MXenes based her electrocatalyst， and the challenges and new opportunities of designing MXenes based electrocatalyst by machine learning. This paper provides a reference for developing a new and efficient MXenes based her electrocatalyst and promoting the green preparation of hydrogen energy in the future.
