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.

Abstract Mesoporous TiO2 has been prepared by a brief and simple sol–gel processing and applied for the removal of Cu(II) from aqueous solution. The adsorption behavior of mesoporous TiO2 for Cu(II) was investigated using batch experiments. Results showed that the pseudo-second-order model and Langmuir isotherm were more accurate to describe the kinetics process and adsorption isotherm. Mesoporous TiO2 adsorbent displayed excellent Cu(II) adsorption efficiency (195.52mg g−1). The thermodynamic parameters showed that the adsorption was spontaneous and endothermic. It was also found that mesoporous TiO2 could be used at least seven times without obvious loss of its original adsorption efficiency. Therefore, the obtained mesoporous TiO2 could be employed as an effective and low-cost adsorbent for removal of Cu(II) from contaminated effluents.
