摘要

值此《表面科学》杂志创刊 60 周年之际,我在此以个人名义介绍了过去三十年来我在该领域做出的一些最重要的贡献。X 射线的利用是这些研究的基础,其中包括用于绘制表面化学键的 X 射线光谱、超快时间尺度的表面反应探测以及操作条件下的 X 射线光电子能谱。通过将电子状态直接投射到吸附原子上,可以探测到 d 带模型中的成键和反键状态。通过对吸附 N2 的两个原子上不同对称性轨道的选择性探测,可以从根本上了解硅原子与表面成键的性质。通过超快光学泵浦和 X 射线激光技术,可以研究 CO 的解吸过程,从而观察到前驱体状态。通过对 Ru 上共吸附的 CO 和 O 的泵探研究,可以检测催化 CO 氧化过程中的过渡态物种。在接近大气压的条件下使用操作型 X 射线光电子能谱,为探测表面化学性质和深入了解氢化反应过程中产生氨、碳氢化合物、甲醇和乙醇的反应机制打开了大门。通过在光谱室中插入一个电化学电池,可以对燃料电池和水分离电催化进行研究,从而深入了解反应机理。

X-ray and photoelectron spectroscopy of surface chemistry; from bonding via femtosecond to operando
For the 60th anniversary of Surface Science, I present here a personal account of some of the most significant contributions I have made to the field over the past three decades. The utilisation of X-rays serves as the foundation for these studies, encompassing X-ray spectroscopy for the mapping of surface chemical bonds, probing of surface reactions on ultrafast timescales, and X-ray photoelectron spectroscopy under operando conditions. The direct projection of electronic states onto the adsorbed atom allowed the detection of bonding and anti-bonding states within the d-band model. The selective probing of orbitals of different symmetries on the two atoms in adsorbed N2 provided a fundamental understanding of the nature of diatomic bonding to surfaces. Ultrafast optical pumping and X-ray laser techniques allowed the study of CO undergoing desorption leading to the observation of the precursor state. Pump-probed studies of co-adsorbed CO and O on Ru enabled the means to detect transition state species during catalytic CO oxidation. The use of operando X-ray photoelectron spectroscopy at near-atmospheric pressures opened the door to probe the surface chemistry and gain insight into the reaction mechanism during hydrogenation reactions to produce ammonia, hydrocarbons, methanol and ethanol. By inserting an electrochemical cell into the spectroscopic chamber, both fuel cell and water splitting electrocatalysis could be studied giving insight about the reaction mechanism.

期刊介绍: Surface Science is devoted to elucidating the fundamental aspects of chemistry and physics occurring at a wide range of surfaces and interfaces and to disseminating this knowledge fast. The journal welcomes a broad spectrum of topics, including but not limited to: • model systems (e.g. in Ultra High Vacuum) under well-controlled reactive conditions • nanoscale science and engineering, including manipulation of matter at the atomic/molecular scale and assembly phenomena • reactivity of surfaces as related to various applied areas including heterogeneous catalysis, chemistry at electrified interfaces, and semiconductors functionalization • phenomena at interfaces relevant to energy storage and conversion, and fuels production and utilization • surface reactivity for environmental protection and pollution remediation • interactions at surfaces of soft matter, including polymers and biomaterials. Both experimental and theoretical work, including modeling, is within the scope of the journal. Work published in Surface Science reaches a wide readership, from chemistry and physics to biology and materials science and engineering, providing an excellent forum for cross-fertilization of ideas and broad dissemination of scientific discoveries.
