Abstract: As the science of catalysis develops with an unprecedented pace in recent years, the quest for new characterization techniques and methodologies to detect physicochemical properties of catalysts related to their catalytic performance and so attain insightful understanding of structure-activity relationship has become of crucial importance in both fundamental research and industrial applications. This review briefly summaries the developments of environmental transmission electron microscopy and in-situ X-ray spectroscopy techniques with emphasis on their applications in the characterization of nanocatalysts and complex surfaces and interfaces in heterogeneous catalysis. These examples confirm the pivotal importance of in-situ techniques in understanding the structure-activity relationship in catalysis and also in facilitating the design of highly efficient catalysts.
