Abstract: Profiting from the advantages of plasmonic metal nanoclusters in material structures, light enhancement, and superior photocatalytic performance, in this study, we elaborately design a newly Bi and Ag dual cocatalyst decorating Bi4Ti3O12 perovskite composite for efficient photocatalytic reaction. Systematic researches reveal that the decoration of Bi and Ag nanoclusters broadens the light absorption range and promotes spatial transfer and separation of photogenerated carriers by the localized surface plasmon resonance (LSPR) effect and the formation of the Schottky-junction. In addition, the Bi and Ag cocatalysts can improve the reaction kinetics of photocatalytic glyphosate removal and hydrogen production effectively. As an encouraging result, the optimized Ag-Bi/Bi4Ti3O12 composite exhibits considerable photocatalytic performance for glyphosate degradation and hydrogen generation; moreover, the superb recycling stabilities (approximately 97.9% and 94.4% retention rates after consecutive cycling reaction) are achieved. Significantly, this work reports, for the first time, the dual cocatalyst/Aurivillius-type bismuth layered oxide perovskite composite for photodegradation of pesticide residues and photosynthesis of hydrogen energy, which provides a new insight for the rational design of cocatalyst/perovskite composite materials to achieve efficient photocatalysis.
