Title: Room temperature synthesis and photocatalytic property of AgO/Ag{sub 2}Mo{sub 2}O{sub 7} heterojunction nanowires

Abstract

Graphical abstract: The AgO nanoparticles are attached on the surface of the Ag{sub 2}Mo{sub 2}O{sub 7} nanowires to form a heterojunction structure. The AgO nanoparticles start embedding into the nanowires with increasing reaction temperature or time. Highlights: ► AgO/Ag{sub 2}Mo{sub 2}O{sub 7} heterojunction NWs were synthesized at room temperature for the first time. ► AgO particles embed into the Ag{sub 2}Mo{sub 2}O{sub 7} NWs with increase in reaction time and temperature. ► The heterojunction NWs display much better photocatalytic activity than the none-heterojunction NWs. ► The catalytic mechanism was proposed. -- Abstract: AgO/Ag{sub 2}Mo{sub 2}O{sub 7} heterojunction nanowires were synthesized at temperatures of 25 °C, 50 °C, 80 °C, and 110 °C, under magnetic stirring in solution reaction. The catalytic activity of AgO/Ag{sub 2}Mo{sub 2}O{sub 7} nanowires was evaluated by the degradation of Rhodmine B dye under the irradiation of the simulated sunlight. The synthesized samples were characterized by X-ray diffractometer, energy dispersive spectrometry, X-ray photoelectron spectrometer, scanning electron microscopy, and transmission electron microscopy. The results show that the AgO nanoparticles are attached on the surface of the Ag{sub 2}Mo{sub 2}O{sub 7} nanowires to form a heterojunction structure. The length of the nanowires is up to 10 μm and themore » size of the AgO nanoparticles is 10–20 nm. The length of nanowires increases with increasing reaction time and temperature while the AgO particles are gradually embedded into the nanowires. The photocatalytic activity is greatly improved for the AgO/Ag{sub 2}Mo{sub 2}O{sub 7} heterojunction nanowires compared with that of the pure Ag{sub 2}Mo{sub 2}O{sub 7} nanowires, indicating a remarkable role of AgO particles on the Ag{sub 2}Mo{sub 2}O{sub 7} nanowires in the photodegradation.« less
