(nitrogen-doped) carbon source (Figure 2.18g) [128]. Another unique procedure
to produce porous nitrogen-doped carbons was based on the natural interactions
between carbohydrates (glucose) and gelating proteins. Depending on the applied
conditions, either nitrogen-doped carbon nanoparticles [129] or monolithic hierar-
chically porous nitrogen-doped carbons were obtained in the absence of sacricial
templates (Figure 2.18h) [130].
2.2.6.3 Heteroatom-Doped HTCs
The introduction of dopants into carbon materials is a useful method of altering their
physical and chemical properties. Successful work thus far includes the ...
