a The multi-shelling schematic. The red is indicative of the large-molecule segment, whereas the yellow denotes the small-molecule segment. b TEM images of double-shell hollow PRNs (mh-PRNs-1) and triple-shell hollow PRNs (mh-PRNs-2). c TEM images of double-shell porous hollow PRNs (mph-PRNs-1) and triple-shell porous hollow PRNs (mph-PRNs-2). d TEM images of double-shell bowl-shaped hollow PRNs (mbh-PRNs−1) and triple-shell bowl-shaped hollow PRNs (mbh-PRNs-2). e TEM images of yolk-shell short chain-shaped porous PRNs (ycp-PRNs) and double-shell short chain-shaped hollow PRNs (dch-PRNs). The scale of TEM images is 400 nm. f In-situ thermogravimetric-mass spectrometric-differential scanning calorimetry was used to document the thermodynamic behavior of phenolic aldehydes from room temperature to 1000 °C. g Schematic representation of the atomic configuration transformation of phenolic-derived amorphous carbon. h Elemental mapping images of phenolic-derived amorphous carbon with different multi-shell structures. Red is element C, green is element N, blue is element O. i High-resolution TEM images of mh-PRNs-2 crystallized at different temperatures, taken with a double spherical aberration-corrected TEM. The scale of High-resolution TEM images is 5 nm.
