Abstract: To bridge the "pressure gap" in catalytic research, continuous efforts have been made over the past several decades towards achieving photoelectron spectroscopy measurements at elevated pressures. With the help of bright synchrotron light sources, the ambient-pressure X-ray photoelectron spectroscopy (APXPS) endstation based on synchrotron radiation facility is widely used in researches on energy, environment and materials. Here, we will briefly summarize the application and development of in-situ APXPS characterization technique in the field of catalysis. Also, we will give our perspective on the development of APXPS in the future.

Key words: ambient-pressure X-ray photoelectron spectroscopy, synchrotron radiation, catalysis, gas/solid interface, liquid/solid interface
