About this Research Topic
Heterogeneous catalysis is extremely complex. Identifying the surface structure of catalysts and understanding the surface chemistry under the reaction condition are critical for designing highly active and selective catalysts. A well-defined catalyst can self-tune its size, structure, and surface composition during reactions to yield functionalities that are out of the expectation based on ex-situ characterizations. Decades ago, the reactor was treated as a “black box” because there was very limited access to atomic-scale information about the state of the catalysts while the catalysis was taking place. This situation in catalyst characterization has been changing dramatically as time goes by and various techniques are able to provide detailed atomic-scale structural and chemical insight into complex heterogeneous catalysts under controlled environments and reaction conditions, which have been termed in-situ and operando characterizations separately. Catalyst in-situ/operando characterization as they evolve in time with a changing chemical environment is critical but still very challenging.
With the development of new techniques, nowadays, quite an impressive array of experimental techniques are available to investigate the catalytic surfaces under operating conditions. Therefore, this Research Topic will focus on new techniques for in situ characterization, new findings, and understanding toward the dynamic nature of the catalytic surfaces and surface chemistry based on in-situ/operando characterization, as well as the reviews on recent advances and perspectives on the future direction.
In this Research Topic we invite researchers to submit Original Research, Reviews and Mini-Reviews exploring, but not limited to, the following Research areas:
• Development of new in-situ/operando characterization techniques
