Photocatalytic performance of biochar-modified TiO2 (C/TiO2) for ammonia–nitrogen removal† † Electronic supplementary information (ESI) available. See DOI: https://doi.org/10.1039/d3ra03789d

ABSTRACT: Biochar-modified TiO2 (C/TiO2) was prepared by a sol–gel method in this study to improve the photocatalytic capacity for ammonia–nitrogen (NH3–N) removal from aqueous solutions. The results showed that biochar was successfully modified on TiO2 and helped improve its photocatalytic performance for pollutant degradation. The removal capacity of ammonia–nitrogen on the synthesized photocatalyst performed well at pH 10 with 1 g L−1 C/TiO2 under both 60 (12.25 mg g−1) and 120 min (16.31 mg g−1) irradiation (xenon lamp, AM1.5, 25 A). Characterization of C/TiO2 through scanning electron microscopy-energy dispersive spectroscopy (SEM-EDS), Brunauer–Emmett–Teller (BET), X-ray diffraction (XRD), X-ray photoelectron spectroscopy (XPS), and Fourier-transform infrared spectrometry (FT-IR) analyses show
