Biochar is produced through pyrolysis or gasification processes that heat biomass in the absence or under reduction of oxygen. Cellulose is the most promising material as it is by far the most abundant and inexpensive saccharide available is used in this experiment. In this experiment we investigate the potential of cellulose precursor for the production and to study the photophysical properties of highly functionalized carbonaceous materials such as hydrochar and biochar via UV-visible, Fluorescence and Raman Spectra. The product yield suggests that the hydrothermal carbonization of cellulose is an effective way to increase the turnover time of carbon contained in the biomass. From a chemical point of view the hydrochar and biochar contain a high amount of oxygen which is present both in the core and the shell of the carbonaceous microspheres.
