▎ 摘　　要

NOVELTY - Preparing MXene-based anode anti-inversion catalyst involves adding MXene into the solvent, and ultrasonically dispersing uniformly to obtain MXene dispersion. The carbon material is added into the solvents, and uniformly dispersing to obtain a carbon material dispersion liquid, the carbon dispersion mixed with the MXene and carbon material three-dimensional composite carrier, transferred to the hydrothermal reaction kettle, introduce nitrogen for 0.1-5 hours, cooling and washing for many times, and drying to obtain the MXenes-carbon material three dimensional composite carrier, the MXes-carbon materials three dimensional compound carrier is placed in the acid solution, and pickled at 20-200degrees Celsius for 0-20 hours. The MXe-carbon product obtained is washed to neutral, dispersing in the solvent and ultrasonic dispersed. USE - Preparation method of MXene base anode anti-inversion catalyst for proton exchange membrane fuel cell used in hydrogen fuel cell vehicle. ADVANTAGE - The MXene base anode anti-inversion catalyst has good conductivity and specific surface area, and good electrolytic selectivity.
