Abstract

Abstract:

To address the environmental pollution caused by the azo dye Congo red（CR）, a pitch-based activated carbon-supported polyaniline/carbon nitride（PANI/CN@AC）composite was prepared via heterojunction construction and morphological control strategies. Subsequently, detailed morphological, crystalline, and photoelectrochemical characterizations were performed. The photocatalytic degradation performance and recycling performance of the PANI/CN@AC composites were evaluated. Furthermore, their charge transfer mechanism and photocatalytic mechanisms were analyzed based on the photoelectrochemical data, active species trapping experiments, and energy band structures. The results show that the semiconductor material CN and the conductive polymer PANI are in close contact, forming a heterojunction, which facilitates efficient separation of photogenerated carriers and broadens the absorption range in the visible-light spectrum. The AC support effectively improves the specific surface area and adsorption performance. Consequently, the PANI/CN@AC composite exhibits excellent photocatalytic and recycling performance. The degradation efficiency of CR under simulated visible-light（λ>420 nm）irradiation reaches 98.97%, and remains at 98.71% after 5 cycles. Mechanistic insights reveal that the conduction band position photoelectron of PANI reduces O₂ to superoxide radicals（·O₂^-）, whereby CR is oxidized and decomposed under the action of active species such as ·O₂^- and holes.
