“…As AgX is composited by Ag + and Cl − , common features for synthesis are definitely existed among them, such as a precipitation reaction of Ag + and X − and ion-exchange between silver salt and HX [122][123][124][125][126][127][128][129][130][131][132][133][134][135]. The architecture and morphology of AgX, especially with high-surface-energy crystalline facets, are able to manage and define their unique photocatalytic properties [136][137][138][139][140][141][142][143][144].…”

The silver halides and their corresponding composites would constitute remarkable photocatalytic systems not only in energy production but also in environmental remediation. The major advantage in these silver halides system is that plasma metal Ag 0 species would be spontaneously generated by silver halides under light irradiation, which play dual roles of expanding light absorption range and charge carriers separation. In this tutorial review, the origin and development of silver halides, synthesis methods, construction of composite structures with other materials, photocatalytic applications, and various and controversial mechanisms are all exhaustively described.

“…In contrast, faster ionic transport was observed along interfaces between two different phases, as for ionic conductors heterogeneously doped with an insulator (e.g. in LiI/Al 2 O 3 or AgCl/Al 2 O 3 [10][11][12][13][14]). The addition of a second phase can Here conductivity values are shown for multilayers with various interfacial densities, i.e.…”

Rapidly growing attention is being directed to the investigation of ionic conductivity in oxide film heterostructures. The main reason for this interest arises from interfacial phenomena in these heterostructures and their applications. Recent results revealed that heterophase interfaces have faster ionic conduction pathways than the bulk or homophase interfaces. This finding can open attractive opportunities in the field of micro-ionic devices. The influence of the interfaces on the conduction properties of heterostructures is becoming increasingly important with the miniaturization of solid-state devices, which leads to an enhanced interface density at the expense of the bulk. This review aims to describe the main evidence of interfacial phenomena in ion-conducting film heterostructures, highlighting the fundamental and technological relevance and offering guidelines to understanding the interface conduction mechanisms in these structures.

“…Further with mesoporous Al 2 O 3 as the insulating phase, the enhancement of conductivity can be more effective, which is satisfactorily explained in the framework of the ideal space-charge model. 31 Here, it is worthwhile mentioning "Soggy Sand Electrolytes". 32,33 The total conductivities are highly increased by virtue of the very high conductivities at the edge of the space charge profiles.…”

This paper is dedicated to Prof. Dr. Janko Jamnik, who was my enthusiastic and helpful MPI colleague as well as with high academic level and reputation in science community. AbstractThe space charge layer (SCL) effects were initially developed to explain the anomalous conductivity enhancement in composite ionic conductors. They were further extended to qualitatively as well as quantitatively understand the interfacial phenomena in many other ionic-conducting systems. Especially in nanometre-scale systems, the SCL effects could be used to manipulate the conductivity and construct artificial conductors. Recently, existence of such effects either at the electrolyte/cathode interface or at the interfaces inside the composite electrode in all solid state lithium batteries (ASSLB) has attracted attention. Therefore, in this article, the principle of SCL on basis of defect chemistry is first presented. The SCL effects on the carrier transport and storage in typical conducting systems are reviewed. For ASSLB, the relevant effects reported so far are also reviewed. Finally, the perspective of interface engineer related to SCL in ASSLB is addressed.
