摘要
催化产氢技术因其高效、清洁的特性而备受关注,其中,催化材料性能的探索与优化是提升氢能产率的关键。X射线光电子能谱技术(XPS)作为一种表面分析技术,能够通过测量光电子的能量分布来解析样品表面的化学信息,包括元素的种类、含量、化学状态及电子结构,为催化产氢研究提供了不可或缺的工具。通过对XPS原理、催化产氢几种常见类型及原理、XPS在几种常见催化产氢材料体系的应用进行归纳,表明XPS不仅能够揭示材料表面活性位点的电子结构与化学环境,还能深入理解催化机理和反应路径,指导材料的理性设计。最后,对XPS技术未来在催化产氢领域的发展进行了展望,随着XPS与其他多种手段的结合,有助于推动催化产氢领域向更深层次的机理探索和高性能材料的开发,这一研究方向不仅促进了催化科学的发展,也为氢能经济的实现提供了强有力的支撑。
Catalytic hydrogen production technology has attracted much attention due to its efficient and clean characteristics,and the exploration and optimization of catalytic material properties is the key to improve the yield of hydrogen energy.X-ray photoelectron spectroscopy(XPS),as a surface analysis technique,can analyze the chemical information of the sample surface by measuring the energy distribution of photoelectrons,including the type,content,chemical state and electronic structure of the elements,which provides an indispensable tool for the study of catalytic hydrogen production.In this paper,the principle of XPS,several common types and principles of catalytic hydrogen production,and the application of XPS in several common catalytic hydrogen production material systems were reviewed,which showed that XPS can not only reveal the electronic structure and chemical environment of active sites on the surface of material,but also deeply understand the catalytic mechanism and reaction path,and guide the rational design of materials.Finally,the future development of XPS technology in the field of catalytic hydrogen production was prospected.With the combination of XPS and other methods,XPS technology can contribute to promoting the deeper mechanism exploration and the development of high-performance materials in the field of catalytic hydrogen production.This research direction not only promotes the development of catalysis science,but also provides strong support for the realization of hydrogen economy.
