Abstract

AbstractA number of papers on the low-dimensional chalcohalide nanomaterials has been increased significantly in recent years due to a lot of unique properties of these compounds. The most important characteristics of the chalcohalides refer to ferroelectric, piezoelectric, pyroelectric, electrocaloric, thermoelectric, photovoltaic, ferroelectric-photovoltaic, photoelectrochemical, photocatalytic, and piezocatalytic properties. The current achievements in research of low-dimensional chalcohalides are summarized in this chapter. The methods of chalcohalide nanomaterials fabrication and their incorporation into functional devices are briefly presented. The applications of the antimony and bismuth chalcohalides are categorized into four main areas: mechanical/thermal energy harvesting along with its storage, photovoltaic devices as well as photodetectos, gas nanosensors, and catalysis for an environmental remediation. The major challenges in fabrication, characterization, and applications of low-dimensional chalcohalide nanomaterials are discussed. Finally, the trends in future investigation of antimony and bismuth chalcohalides are predicted.KeywordsChalcohalide nanomaterialsEnergy harvestersSensorsSupercapacitorsPhotovoltaic devicesGas sensorsPhotocatalysts
