Trace amount multi-walled carbon nanotubes (MWCNT) modified BiOBr were successfully fabricated via a one-step solvothermal method for efficient and stable degradation of tetracycline hydrochloride (TC). The MWCNT/BiOBr photocatalysts exhibited excellent photocatalytic with low PL intensity, high photocurrent, and small EIS arc at the optimal loading amount of MWCNT 0.01mg (0.001wt%), The significant enhancement of as-prepared MWCNT/BiOBr may be assigned to the high capture electron capability of MWCNT, which not only enhance the absorption of lights but also accelerate the separation of photogenerated charge carriers. Based on the trapping experiment and electron spin resonance (ESR), the possible mechanism of enhancing the photocatalytic activity for the composites was also proposed, in which the ∙O2 - was deemed to the primary active oxidants.
