Ag/AgBr photocatalysts are prepared by a ionic-liquid-assisted hydrothermal method. The as-prepared photocatalysts are characterized by scanning electron microscopy, X-ray powder diffraction, X-ray photoelectron spectroscopy, Brunauer-Emmett-Teller measurement, and diffuse reflectance spectroscopy. Ag/AgBr exhibits significant photocatalytic activity toward degradation of imidacloprid under visible light. After 9 h, the conversion percentage of imidacloprid reaches 90%. Besides, the cycle performances suggest a good stability of the catalyst. The photocatalytic kinetics indicate that the degradation processes follow pseudo-first-order kinetics. According to the fact that electron holes • OH and • O 2 À greatly promote the photodegradation process, the degradation mechanism is proposed.

Recently, near‐infrared light (NIR) photocatalysts, such as up‐converting materials, Bi2WO6, Cu2(OH)PO4, and carbon quantum dots, have been found and are attracting attention for environmental cleaning and energy conversion, because NIR light constitutes nearly half of the energy output. However, the photocatalytic efficiency is low for these new types of NIR photocatalysts, which has limited their widespread application owing to their insufficient NIR‐light absorption. In this work, we use gold (Au) nanorods to enhance the NIR‐light absorption of Bi2WO6, a typical visible and novel NIR‐light photocatalyst, thus the enhancement of its NIR‐light photocatalytic and photoelectrochemical properties are achieved. This can be attributed to the surface plasmon resonance (SPR) effects and wide‐range NIR light harvesting of the Au nanorods. The present work provides key guidelines for the improvement of NIR‐light photocatalysts and could also help design and prepare novel photocatalysts.
