摘要：Two-dimensional vertically aligned Bi2O3 nanosheets over carbon paper (CP) were prepared via an in situ growth approach. Bi2O3/CP exhibits a robust photocatalytic activity, as well as renewability and flexibility. With Rhodamine B and 2,4-dichlorophenol used as target pollutants, the rate constant of Bi2O3/CP was 3.72 × 10?3 min?1 and 6.93 × 10?3 min?1 under visible-light irradiation for 2 h, respectively. The improved activity was attributed to the synergistic effects of the hierarchical structure of Bi2O3 and the conductive substrate, CP; the former provided efficient catalytic sites for the pollutants and absorbed more of the light scattered among the nanosheets, while the latter is beneficial to the photogenerated electron transfer. ? 2022 The Royal Society of Chemistry.
