Fig. 2: Encapsulation of CoPc within CNTs.
From: Nanoconfinement promotes CO2 electroreduction to methanol on a molecular catalyst
a Schematic illustration depicting the encapsulation of CoPc inside CNTs with varying IDs. The inset presents the molecular structure of CoPc. b, c, HR-TEM images (left) of CoPc/CNT(I) (b) and CoPc/CNT(III) (c), accompanied by corresponding structural models (middle) and simulated TEM images (right). The regions with darker contrast, attributed to Co atoms, are highlighted with yellow circles. d HR-TEM (top) and HADDF-STEM (bottom) images of CoPc/CNT(III) at the same location, confirming the successful encapsulation of CoPc molecules.
