电解水产氢作为一种可持续的清洁能源生产方式,开发更加高效稳定的电催化材料对于促进可再生能源的发展具有重要的意义。硒化镍化合物作为一种新型的电催化剂材料,近年来受到了广泛的关注。与其它常见金属催化剂相比,硒化镍化合物有许多优势,例如更高的化学稳定性和较大的化学电导率,而且,硒化镍化合物具有可调节的导电性、表面积和表面化学活性,使其在水电解反应中展现出良好的电催化性能。掺杂钼的硒化镍纳米材料已经显示出对析氢反应的有希望的催化活性,使它们成为用于水电解的潜在候选材料。钼金属掺杂硒化镍纳米材料的构建及其电解水性能是材料科学和能源研究领域中具有重要意义和价值的课题。本工作合成了一种Mo-Ni5Se5三维孔洞纳米材料,该材料是在Ni5Se5材料上使用含Mo溶液进行离子交换得到了。正如预期的那样,我们所制备的这种材料在HER/OER方面都显示了良好的电催化全解水性能。这些发现为未来钼基硒化镍材料的工业化应用提供了一种优秀的思路。As a sustainable and clean energy production method, the development of more efficient and stable electrocatalytic materials is of great significance to promote the development of renewable energy. Nickel selenide, as a new kind of electrocatalyst material, has received extensive attention in recent years. Compared with other common metal catalysts, nickel selenide compounds have many advantages, such as higher chemical stability and greater chemical conductivity, and nickel selenide compounds have adjustable electrical conductivity, surface area and surface chemical activity, so that they show good electrocatalytic properties in the water electrohydrolysis reaction. Molybdenum doped nickel selenide nanomaterials have shown promising catalytic activity for hydrogen evolution reactions, making them potential candidates for use in hydroelectrolysis. The construction of molybdenum metal-doped nickel selenide nanomaterials and their water electrolysis performance are important and valuable topics in the field of materials science and energy research. In this work, Mo-Ni5Se5 three-dimensional porous nanomaterial was synthesized. The nanomaterial was obtained by ion exchange with Mo solution on Ni5Se5 material. As expected, the materials we have prepared have shown good electrocatalytic properties in HER/OER. These findings provide an excellent idea for the industrial application of molybdenum-based nickel selenide materials in the future.
