Abstract

A composite of pyrolytic Triarrhena biochar loading with TiO 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 TiO. The results suggest that biochar loading with TiO could be promisingly implemented as an environmentally friendly and inexpensive adsorbent for Congo red removal from wastewater.

摘要

采用溶胶-凝胶法合成了负载TiO纳米颗粒的热解荻草生物炭复合材料。通过XRD、BET和SEM表征发现，该复合材料具有发达的中空介孔和大孔结构。当用作从水溶液中去除刚果红的吸附剂时，发现所制备的复合材料比单一生物炭或TiO具有更好的吸附能力。结果表明，负载TiO的生物炭有望作为一种环境友好且廉价的吸附剂用于从废水中去除刚果红。
