Efficient photoelectrocatalytic performance of beta-cyclodextrin/graphene composite and effect of Cl^- in water: degradation for bromophenol blue as a case study.

ABSTRACT: Photoelectrocatalytic technology has proven to be an efficient way of degrading organic contaminants, including dyes. Graphene (GR) -based catalysts have been frequently used in photoelectrocatalysis, due to their excellent catalytic performances. In this work, the GR/beta-cyclodextrin (GR/β-CD) composite was prepared and used for a widely used triphenylmethane dye (bromophenol blue, BPB) photoelectrocatalytic degradation. The results indicated that the degradation of the prepared GR/β-CD composite for BPB was effective with the combination of external bias voltage and simulated sunlight irradiation. Under optimum conditions, the BPB (10 mg L^-1) was completely eliminated by GR/β-CD composite within 120 min. ˙O₂ ^- played a prominent role in the BPB photoelec
