Three silver‐based photocatalysts, Ag@AgBr, Ag 2 Mo 2 O 7 , and Ag 2 MoO 4 ‐MoO 3 , were successfully synthesised by a smart hydrothermal strategy using molybdenum oxide as precursor in surfactant‐assisted processes. The correlation among crystal structure and properties in the photocatalysts are discussed in detail. In addition to morphology control, the bromine source effect of adding surfactant cetyltrimethyl ammonium bromide in hydrothermal synthesis of plasmonic silver incorporated silver bromide photocatalyst was also found. The obtained Ag@AgBr showed higher photocatalytic activity in the degradation of methylene blue than other samples due to super sensitivity of AgBr to light and the surface plasmon resonance of Ag nanoparticles in the region of visible light.
