In this study, the influence of boron doping on structural and surface
properties of carbon material synthesized by hydrothermal method was
investigated, and the obtained results were compared with the previously
published influence that boron has on characteristics of carbonized
boron-doped hydrothermal carbons (CHTCB). Hydrothermal carbons doped with
boron (HTCB), were obtained by hydrothermal synthesis of glucose solution
with the different nominal concentrations of boric acid. It was found that
glucose based hydrothermal carbon does not have developed porosity, and the
presence of boron in their structure has insignificant influence on it. On
the contrary, additional carbonization increases the specific surface area
of the undoped sample, while the increase in boron content drastically
decreases specific surface area. Boron doping leads to a decrease in the
amount of surface oxygen groups, for both, hydrothermally synthesized and
additionally carbonized material. Raman analysis showed that boron content
does not affect the structural arrangement of HTCB samples, and Raman
structural parameters show higher degree of disorder, compared to the CHTCB
samples. Comparison of structural and surface characteristics of
hydrothermal carbons and carbonized materials contributes to the study of
the so far, insufficiently clarified influence that boron incorporation has
on the material characteristics.
