      abstract     = {Nitrogen‐containing hydrothermal carbon (N‐HTC)
                      materials of spherical particle morphology were prepared by
                      means of hydrothermal synthesis with glucose and urotropine
                      as precursors. The molar ratio of glucose to urotropine has
                      been varied to achieve a continuous increase in nitrogen
                      content. By raising the ratio of urotropine to glucose, a
                      maximal nitrogen fraction of about $19 wt \%$ could be
                      obtained. Decomposition products of both glucose and
                      urotropine react with each other; this opens up a variety of
                      possible reaction pathways. The pH has a pronounced effect
                      on the reaction pathway of the corresponding reaction steps.
                      For the first time, a comprehensive analytical
                      investigation, comprising a multitude of analytical tools
                      and instruments, of a series of nitrogen‐containing HTC
                      materials was applied. Functional groups and structural
                      motifs identified were analyzed by means of FTIR
                      spectroscopy, thermogravimetric MS, and solid‐state NMR
                      spectroscopy. Information on reaction mechanisms and
                      structural details were obtained by electronic structure
                      calculations that were compared with vibrational spectra of
                      polyfuran or polypyrrole‐like groups, which represent
                      structural motifs occurring in the present samples.},
