为改善这一缺点，科学工作者尝试过多种优化手段，例如采用掺杂-杂原子（阳

In order to improve this shortcoming, scientists have tried various optimization methods, such as the use of doping-heteroatoms (cations or anions) or carrier composite materials, which can increase the electron density near the carbide Fermi level and regulate the electrode The d-electron band of the material promotes the dissociation and desorption of adsorbed hydrogen, thereby obtaining an electrocatalytic material with high activity

In order to improve this shortcoming, scientists have tried a variety of optimization methods, such as the use of doped-heatoms (yang or anion) or carrier composite materials, etc., can improve the electron density near the feminate level, regulate the d electron belt of electrode material, promote the decoupling of adsorption hydrogen, so as to obtain a highly active electrocatalytic material
