چکیده انگلیسی
Heterogeneous photocatalysis namely titanium dioxide (TiO2) supported on coconut shell biochar (BC) was synthesized by sol-gel method (calcined at 450â¯Â°C) in the paper, which was innovatively applied to the decolorization of Reactive Brilliant Blue KN-R. The transmission electron microscopy (TEM) and X-ray diffraction patterns (XRD) results demonstrated that anatase TiO2 film was firmly immobilized on the surface and pores of BC. The photocatalysis tests under UV high pressure xenon lamp (300â¯W) showed highest decolorization efficiency occurred at strong acid and alkali conditions (pHâ¯=â¯1 and 11) reached as 99.71% and 96.99% respectively within 60â¯min. Therefore, the TiO2/BC composites demonstrated both photocatalytic and adsorption capacity on KN-R decolorized, and presented quite durable and reusable in regeneration cycles, indicating a widely application possibility in anthraquinones dyeing wastewater treatment.
