Synthesis, characterization and material properties of titanium carbide nanocomposite derived from biochar

Abstract Titanium carbide was synthesized from biochar, an agricultural waste material. Sol-gel technology was used to develop organic-inorganic hybrid of titania and biochar. The hybrid was carbothermally reduced at a higher temperature of 1450 °C in an inert atmosphere. Reduction of as-prepared TiC at different concentrations, resulted in production of khamrabaevite TiC polytypes. The lattice constants obtained for TiC phase in different samples were 0.45964 nm and 0.45112 nm respectively, indicating a decreasing order with increasing contents of Ti- contents.
