CatalystsH 2000 Ag@AgCl: A Highly Efficient and Stable Photocatalyst Active under Visible

Light. — Ag@AgCl particles consisting of Ag0 nanoparticles (20-150 nm in diameter) on the surface of AgCl particles (0.2—1.3 μm) are synthesized by treating Ag2MoO4 (hydrothermally from AgNO3 and Na2MoO4, autoclave, 180 °C, 1 h under microwave irradiation) with HCl to form AgCl powder followed by visible light irradiation. The samples are characterized by XRD, SEM, and diffuse reflectance UV/VIS spectrosco-py. The Ag@AgCl particles exhibit a highly efficient photocatalytic activity for meth-ylic orange dye degradation in solution under visible light irradiation. Plasmonic pho-tocatalysts such as Ag@AgCl are promising candidates for the development of efficient and stable photocatalysts active under visible light. — (WANG, P.; HUANG*, B.; QIN, X.; ZHANG, X.; DAI, Y.; WEI, J.; WHANGBO, M.-H.; Angew.
