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.

生物炭衍生碳化钛纳米复合材料的合成、表征及材料性能

摘要 碳化钛是由农业废弃物生物炭合成的。溶胶-凝胶技术被用于开发二氧化钛和生物炭的有机-无机混合物。在惰性气氛中，在 1450°C 的较高温度下对杂化物进行碳热还原。减少不同浓度下制备的 TiC，导致产生 khamrabaevite TiC 多型体。不同样品中 TiC 相的晶格常数分别为 0.45964 nm 和 0.45112 nm，表明随着 Ti- 含量的增加而递减。
