Figure 10. (A) Concept of the cooperative characterization approach. (1) In situ TEM observes the morphological evolution of the material under different calcination conditions. (2) Cantilever-TGA gives the detailed calcination temperature and duration. (3) Cooperative characterization with in situ TEM and cantilever-TGA provides a comprehensive calcination parameter and can tune the product characteristics. (B) Calcination results of MnO₂ nanowires under an N₂ atmosphere. (1) SEM image of the resonant microcantilever for the cantilever-TGA measurements. (2) Cantilever-TGA curve of the MnO₂ nanowires under an N₂ atmosphere. Two mass-loss stages can be distinguished and correspond to the production of Mn₂O₃ and Mn₃O₄, respectively. (3) In situ TEM results of the MnO₂ nanowires under an N₂ atmosphere. (4) SAED patterns of the sample obtained at different temperatures. (5) Cs-corrected TEM images of the sample obtained at 600 °C for 1 h^[70]. Copyright 2023, American Chemical Society.
