The Ambient-Pressure X-ray Photoelectron Spectroscopy (APXPS) endstation at the SPECIES beamline at MAX IV Laboratory has been improved. The latest upgrades help in performing photo-assisted experiments under operando conditions in the mbar pressure range using gas and vapour mixtures whilst also reducing beam damage to the sample caused by X-ray irradiation. This article reports on endstation upgrades for APXPS and examples of scientific cases of in situ photocatalysis, photoreduction and photo-assisted atomic layer deposition (photo-ALD).
MAX IV 实验室 SPECIES 光束线上的环境压力 X 光电子能谱（APXPS）端站得到了改进。最新的升级有助于在毫巴压力范围内使用气体和蒸气混合物在原位条件下进行光辅助实验，同时减少 X 射线照射对样品造成的束损伤。本文介绍了 APXPS 的端站升级以及原位光催化、光还原和光辅助原子层沉积（光-ALD）的科学案例示例。
