AgCl cubical hollow nanoframes were primarily prepared using sacrificial NaCl template protocol. Ion exchange reaction between Ag+ in the solution and NaCl, in presence of poly(vinylpyrrolidone) (PVP) led to continuous nucleation followed by growth of AgCl on the surface of sacrificial NaCl template. The tuning of AgCl nanoframe structures was obtained by changing the AgNO3 concentration in the reactions. Afterwards, ethylene glycol assisted reduction of AgCl, produced Ag@AgCl, the metal@semiconductor composite with the homogeneous distribution of Ag nanoparticles on the surface of the AgCl hollow nanoframes. Efficient sunlight-driven photocatalytic activity to degrade Methylene blue (MB) (50 mL; 10 mg/L) with these Ag@AgCl hollow frames was also demonstrated. The plasmonic photocatalysts were exhibited photodegradation rates about 0.098–0.184 min−1 with high catalytic activity and recyclability for five cycles. Additionally, active species entrapping experiments were performed and a possible mechanism for the enhanced photocatalytic performance of the synthesized plasmonic photocatalyst was also proposed.1 aS., Hanmant, Gaikwad1 aKoratti, A.1 aPorel, Mukherjee, S.  uhttps://library.ncl.res.in/content/facile-tuning-agagcl-cubical-hollow-nanoframes-efficient-sunlight-driven-photocatalytic
