Description:	The objective of this work was to characterize the morphology and molecular composition of the hydrochar produced by microwave‑assisted hydrothermal carbonization of cellulose. The produced hydrochar consists mainly of aggregate microspheres with about 2.0 μm in diameter, with aliphatic and aromatic structures and the presence of carbonyl functional groups. The aromatic groups are formed mainly by benzofuran‑like structures, being chemically different from common cellulose char. Microwave‑assisted hydrothermal carbonization yields a functionalized carbon‑rich material similar to that produced by the conventional hydrothermal process.
