近室壓光電子能譜術於化學相關領域應用簡介
A Short Introduction to Near-ambient Pressure X-ray Photoelectron Spectroscopy
摘要
光電子能譜術（X-ray Photoelectron Spectroscopy, XPS）是應用成熟的真空環境下表面分析技術。二十年來，由於儀器的改良設計，固態樣品處於濕潤狀態或置於毫巴氣壓下的光電子能譜都能夠被量測。這些能譜分別帶有豐富的液／固介面、氣／固介面訊息，因此常被用於介面研究，被稱為近室壓光電子能譜術（Near Ambient Pressure X-ray Photoelectron Spectroscopy, NAPXPS 或APXPS）。自2017年TLS 24A近室壓光電子能譜實驗站搭建完成以來，近室壓光電子能譜術在台灣生根發展已經有六年。平均每半年有近三十個來自國內外大專院校、研究機構的化學、物理、材料科學的研究團隊來到國家同步輻射研究中心進行相關實驗。研究成果也持續在學術期刊上發表。然而，對於不常造訪國輻使用近室壓光電子能譜實驗站的研究人員與學生，此技術仍然相對陌生。本文從學理技術、儀器發展、研究上的應用等面向，概略介紹近室壓光電子能譜術，以期提供一個認識近室壓光電子能譜術的切入點。
並列摘要
X-ray photoelectron spectroscopy (XPS) has been well developed for surface analysis under ultra-high vacuum condition. Over the past two decades, instrumentation advancement has enabled the measurement of XPS from a solid sample placed in either elevated gas pressure or a wetted environment. These photoelectrons carry ample information of the interfaces and has been used in studying gas/solid and liquid/solid interfaces. The methodology is called Near-Ambient Pressure X-ray Photoelectron Spectroscopy (NAPXPS or APXPS). Since the establishment of the APXPS endstation at TLS 24A in 2017, the related community in Taiwan has been keep on growing. In every half-year cycle, the endstation hosts nearly thirty research groups from universities and research institutes worldwide to conduct chemistry, physics, and materials experiment. However, the technique is relatively unfamiliar to researchers and students who do not visit NSRRC for APXPS experiments. The purpose of this article is to provide a starting point for those who are not yet in the field but are interested to step in.
