通过简单实验操作改变实验压力，调节碳化钼超薄纳米片表面磷原子覆盖度，增

By changing the experimental pressure through a simple experimental operation, adjusting the coverage of phosphorus atoms on the surface of the ultra-thin molybdenum carbide nanosheets, increasing the number of "local" highly active hydrogen evolution sites to obtain the phosphorus content under optimal hydrogen evolution activity, and further improving the hydrogen evolution of P-Mo2C active

Through simple experimental operation to change the experimental pressure, adjust the surface phosphorus atom coverage of the ultra-thin nanochip carbide, increase the number of high-activity hydrogen analysis sites in the "local area", obtain the phosphorus content under optimal hydrogen analysis activity, and further improve the hydrogen analysis activity of P-Mo2C
