摘要:
以二维共轭碳氮化物和钼酸铵为前驱体合成材料载体,并以水热方式将活性金属钌均匀分散在载体上,制备了一种MoC修饰钌纳米粒子的非铂电催化剂,用于电化学析氢性能研究,且结构中包含了N掺杂原子和纳米孔。这些孔在材料中创造了高度易接近的催化位点和良好的电荷传输,从而为HER提供了良好的反应动力学。N掺杂原子可以调节材料中催化活性位点的电子性质,使参与反应的氢组分吸附和解吸自由能降低,对HER具有较好的催化活性。
Abstract:
A non-Pt electrocatalyst for porous carbon molybdenum carbide with ruthenium nanoparticles was prepared in this paper. The carrier was synthesized by using two dimensional conjugated carbonit and ammonium molybdate as precursors, and the active metal ruthenium was uniformly dispersed with the support of hydrothermal method. Their structure consists of N-doped atoms and nanopores. These holes create highly accessible catalytic sites and good charge transfer ability in the material, thus providing good reaction kinetics for hydrogen evolution reaction(HER). N-doped atoms regulate the electronic properties of the catalytic active sites in the material, which reduces the free energy of adsorption and desorption of hydrogen components participating in the reaction, providing good catalytic activity for HER.
