The global serious pollution situation urgently needs green, efficient, and sustainable development methods to achieve heavy metal control. photocatalytic properties of anatase are sufficient control by providing photoelectrons harmful metals. However, since natural particles tend agglomerate deactivate in water, most studies have been conducted prepare TiO2–biochar nanocomposites using chemical synthesis methods. In the present study, we utilized pyrolytic sintering load onto biochar obtain anatase–biochar (TBC) composites. Characterization tests, such as X-ray diffraction (XRD), scanning electron microscopy (SEM), photoelectron spectroscopy (XPS), showed that was uniformly partitioned into surface pores without destroying lattice structure. Due its properties, TBC degraded Cr (VI) 99.63% under light conditions. This is 1.58 times higher than dark condition. Zeta potential positively charged acidic charge attraction between chromium salt involved efficient degradation (VI). Different sacrificial agents well gas purge experiments demonstrated (e−) superoxide radicals (O2−) dominated has characteristics high efficiency, stability, sustainability. may provide a new idea for preparation materials realization environmental protection through

Abstract Biochar (BC) derived from reed stems was prepared by high-temperature pyrolysis, and two types of ZnO/biochar (ZBC) TiO 2 /biochar (TBC) composite materials were synthesized via a simple hydrolysis method. These composites, compared to pure ZnO , exhibit not only improved but significantly enhanced crystalline structures larger specific surface areas. This enhancement in the physical chemical properties ZBC TBC composites is crucial aspect our research, as it leads distinct red-shifted absorption edge excellent visible-light characteristics. The photocatalytic degradation efficiency materials, key finding study, evaluated using doxycycline antibiotic simulated pollutant under irradiation. results demonstrate 6.0-fold 7.3-fold increase respectively, further underscoring significance these properties. Furthermore, active species trapping experiments reveal that ·OH radicals are dominant reactive process doxycycline. A Langmuir–Hinshelwood kinetic model accurately represents this process. Kinetic data indicate rate constants ( k ) catalysts 4.314 × 10 −2 min −1 3.416 respectively. photocatalysts no significant decrease for even after fourth cycle, indicating their relatively high reusability. suggest can be used stable, efficient, cost-effective, sustainable antibiotic-contaminated wastewater treatment.
