“…AgCl has direct and indirect band gap of 5.15 eV (~ 240 nm) and 3.25 eV (~ 380 nm), respectively. 20 Therefore, absorption of light above 380 nm is not possible by AgCl alone. On the other hand, it has been shown that Ag nanoparticles deposited on AgCl show the plasmonic absorption of visible light.…”

We demonstrate a facile route to synthesize silver chloride nanocubes and derivative nanomaterials. For the synthesis of silver chloride nanocubes, silver nitrate and hydrochloric acid were used as precursors in ethylene glycol, and poly (vinyl pyrrolidone) as a surfactant. Molar ratio of the two precursors greatly influenced the morphology and composition of the final products. As-synthesized silver chloride nanocubes showed size-dependent optical properties in the visible region of light, which is likely due to a small amount of silver clusters formed on the surface of silver chloride nanocubes. Moreover, we show for the first time that simple reduction of silver chloride nanocubes with different reducing reagents leads to the formation of delicate nanostructures such as cube-shaped silver-nanoparticle aggregates, and silver chloride nanocubes with truncated corners and with silver-nanograin decorated corners. Additionally, we quantitatively investigated for the first time the evolution of silver chloride nanocubes to silver chloride nanocubes decorated with silver nanoparticles upon exposure to e-beam. Our novel and facile synthesis of silver chloride related nanoparticles with delicately controlled morphologies could be an important basis for fabricating efficient photocatalysts and antibacterial materials.

“…The weak absorption in the visible region is due to the large bandgaps of AgCl, i.e., a direct bandgap of 5.15 eV (241 nm) and an indirect bandgap of 3.25 eV (382 nm). [37] Heating the dispersion at elevated temperatures, for example, 160 8C for 30 min, changes the color to pale red (Supporting Information, Fig. S1).…”

Photocatalysis is the acceleration of a photoreaction in the presence of a catalyst and is becoming promising in many applications with the utilization of solar energy. Typical examples include conversion of water to hydrogen gas (a clean energy carrier) by photocatalytic water splitting, [1][2][3][4][5][6] creation of self-cleaning surfaces, [7][8][9] disinfection of water, [10] oxidation of organic contaminants, [11]

“…AgCl is a semiconducting material with an indirect band gap of 3.3 eV (% 380 nm). [18] The photoactivity of AgCl extends from the UV into the visible-light region due to self-sensitization, caused by the formation of silver species during the photoreaction. Concisely, the overall reaction can be seen as the oxidation of water to dioxygen plus protons and the reduction of silver cations to silver upon illumination.…”
