摘要：An unusual hollow core expansion through in situ self-activation in a confined nanospace is observed, which is due to the different physical and chemical properties of the core and shell. The in situ generated gas molecules (e.g., CO2, H2O) preferentially assemble in the hollow core and create immense pressure, which can gasify the formed carbon shells, resulting in substantially increased porosity and a hollow cavity.
