“…/ AgCl/Ag n photoanode and the amorphous Si solar cell led to photoelectrochemical water splitting to O 2 and H 2 ; see Fig. 10 (left) [74]. In other yet preliminary experiments we prepared zeolite monolayers on conducting surfaces like gold coated glass and gold foil [75].…”

One-dimensional channel materials, such as zeolites and mesoporous silicas, are very attractive hosts for the preparation and investigation of hierarchically organized structures, presenting a successive ordering from the molecular up to macroscopic scale. The focus of this article is on artificial photonic antenna systems and on photocatalytically active layers that have been built by incorporating organic dyes, complexes, metal cations and clusters into 1-D nanochannel materials. We show that zeolite L as a host material allows for the design and preparation of a large variety of highly organized hostguest systems. The combination of a tuneable host morphology and the possibility of obtaining highly organized molecular patterns of guests leads to a variety of potential optical and photoelectronic applications. Strongly absorbing systems exhibiting efficient FRET along the c-axis of the zeolite crystals are accessible by sequential inclusion of multiple types of dyes. These new light-harvesting materials offer unique possibilities as building blocks for solarenergy conversion devices. A complementary approach consists in integrating photochemically active substances into zeolite monolayers coated on an electrode and taking advantage of intrazeolite processes for designing a reversible electrode for photocatalytic water oxidation. The photoelectrochemical water splitting capability of systems based on Ag ? /AgCl/Ag n -zeolite photoanodes are discussed.

“…1,2 It also has photocatalytic activities that are useful for water splitting and decomposition of organic pollutants. [3][4][5][6] It has been demonstrated that decoration of AgCl with Ag nanoparticles can greatly improve the light absorption property and photostability of the AgCl nanoparticles. [7][8][9] In addition, AgCl can be used in fabricating antiseptic catheters, bone cements, and fabrics owing to its antibacterial property.…”

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.

“…To allow sufficient ionic transport when no separators are present, often highly acidic or basic electrolytes are used (Seger and Kamat, 2009;Chen Q. et al, 2013;Currao et al, 2004). These have the disadvantage of being corrosive and expensive which makes them difficult to apply on a large scale as highly resistant reactor materials must be used throughout the system.…”

-Solar driven water splitting can be achieved by coupling electrolyzers with PhotoVoltaics (PV). Integration of both functions in a compact PhotoElectroChemical (PEC) cell is an attractive option but presents significant scientific challenges. In this work, the design of single-and dualcompartment PEC cells for research purposes is discussed. The fabrication of separator-electrode assemblies is an important aspect, and upscaling of these architectures even to centimeter scale is not trivial. The layout of a new dual-compartment compact PEC cell with in-situ monitoring of pH, temperatures, and oxygen and hydrogen evolution for research purposes is presented. Finally, a prospect of future PEC cells for practical applications is presented.Résumé -Conception de cellules photoélectrochimiques compactes pour la décomposition de l'eau -La décomposition de l'eau en utilisant la lumière du soleil s'effectue par couplage d'un électrolyseur aux cellules PhotoVoltaïques (PV). L'intégration des deux fonctions dans une seule cellule PhotoElectroChimique (PEC) compacte est envisagée, mais présente un très grand défi scientifique. Cet article traite la conception des cellules PEC de recherche avec ou sans compartimentation. L'assemblage de séparateurs et d'électrodes est un aspect important, et la fabrication de ces architectures, même à l'échelle centimétrique et n'est pas évidente. La disposition d'une nouvelle cellule compacte PEC à deux compartiments permettant de contrôler in situ l'évolution du pH, de la température, et les concentrations d'oxygène et d'hydrogène est présentée. Enfin, une perspective de futures cellules PEC pour des applications pratiques est présentée.
