摘　　要：Chemical electron microscopy(CEM),a toolbox that comprises imaging and spectroscopy techniques,provides dynamic morphological,structural,chemical,and electronic information about an object in chemical environment under conditions of observable performance.CEM has experienced a revolutionary improvement in the past years and is becoming an effective characterization method for revealing the mechanism of chemical reactions,such as catalysis.Here,we mainly address the concept of CEM for heterogeneous catalysis in the gas phase and what CEM could uniquely contribute to catalysis,and illustrate what we can know better with CEM and the challenges and future development of CEM.
