采用溶胶-凝胶法制备了负载纳米TiO 2的热解生物炭复合材料。通过XRD、BET和SEM等手段对复合材料进行表征，结果表明该复合材料具有良好的中空介孔和大孔结构。将其作为吸附剂用于去除水中的刚果红，发现其吸附性能优于单一生物炭或TiO 2。结果表明，负载TiO 2的生物炭可以作为一种环境友好和廉价的吸附剂用于去除废水中的刚果红。
A composite of pyrolytic Triarrhena biochar loading with TiO2 nanoparticles has been synthesized by the sol-gel method. The composite shows a well-developed hollow mesoporous and macropore structure as characterized by XRD, BET, and SEM. When used as an absorbent to remove Congo red from aqueous solution, it was found that as-prepared composite performed better absorption capacity than single biochar or TiO2. The results suggest that biochar loading with TiO2 could be promisingly implemented as an environmentally friendly and inexpensive adsorbent for Congo red removal from wastewater.
