摘要 Understanding the relationship between the properties and performance of black titanium dioxide with core-shell structure(CSBT)for environmental remediation is crucial for improving its prospects in practical applications.In this study,CSBT was synthesized using a glycerol-assisted sol-gel approach.The effect of different water-to-glycerol ratios(W:G=1:0,9:1,2:1,and 1:1)on the semiconducting and physicochemical properties of CSBT was investigated.The effectiveness of CSBT in removing phenolic compounds(PHCs)from real agro-industrial wastewater was studied.The CSBT synthesized with a W:G ratio of 9:1 has optimized properties for enhanced removal of PHCs.It has a distinct coreshell structure and an appropriate amount of Ti3+cations(11.18%),which play a crucial role in enhancing the performance of CSBT.When exposed to visible light,the CSBT performed better:48.30%of PHCs were removed after 180 min,compared to only 21.95%for TiO_(2) without core-shell structure.The CSBT consumed only 45.5235 kWh/m^(3) of electrical energy per order of magnitude and cost$2.4127 per unit volume of treated agro-industrial wastewater.Under the conditions tested,the CSBT demonstrated exceptional stability and reusability.The CSBT showed promising results in the treatment of phenols-containing agro-industrial wastewater.
