Abstract
In this contribution, we have utilized Jasmine flower (Tabernaemontana divaricata) extract as a green source during the synthesis of carbon under hydrothermal conditions. Phase characterization indicated that the prepared material is graphitic carbon with various functional groups. TEM images revealed that the prepared material is composed of quasi-spherical particles having diameters in the 15 nm range, which are accumulated in micro-spherical ones as indicated by SEM images. N2-adsorption measurements indicated that this spherical carbon possesses a mesoporous character. XPS data revealed the co-existence of various C, N, and O species at the surface of this carbon. Sodium borohydride (NaBH4) hydrolysis activity of the synthesized carbon was investigated over the 25–45 °C range of temperature. The catalytic activity was found to increase with both the temperature and NaBH4 concentration (up to 5 wt. %). Moreover, the activity was quenched in the presence of strong bases.
