Titania-supported silver nanoparticles: An efficient and reusable catalyst for reduction of 4-nitrophenol

► Environmentally benign and efficient method ► Stable silver NPs better for catalysis ► Elemental silver NPs instead of their oxides ► Effective capping of silver NPs by sodium dodecyl sulfate in aqueous medium ► Excellent catalyst towards reduction of p-nitrophenol to p-aminophenol at RT.
