“…Mathew et al reported the synthesis of CuS nanoparticles through the photochemical method. They established the correlation between the amount of particles and the time of irradiation [11]. Krishnamoorthy et al demonstrated the synthesis of CuS nanoparticles for supercapacitor applications through a one-pot hydrothermal approach [12].…”

“…However, because of the toxicity and high material cost of LiCoO 2 , there is growing interest in replacing such cathodes. Among the various candidates for cathode materials, metal sulfides such as TiS 2 [1], CuS [2], NiS [3], and FeS 2 [4] are promising because of their low material cost and high energy density. Accordingly, various metal sulfides that can replace the commercially used cathode material have been studied extensively.…”

“…Nanoparticles of CdS [23,24,[26][27][28], PbS [25], and ZnS [27] and also nanocrystalline films of CdS and Cd x Zn 1-x S [29], Cu x S [30,31], Bi 2 S 3 , and (Bi x Sb 1-x ) 2 S 3 [32] were produced by this method. The formation of S II from thioacetamide arises as a result of the absorption of UV light quanta (253.7 nm) according to the following scheme [20]:…”

“…The possibility of such a mechanism is subject to doubt since this reaction can take place during the action of quanta with l < 242 nm [33], whereas less energetic radiation with l > 290 nm was used in [22,23]. More valid is the mechanism proposed in [24,26,31], according to which the main light-absorbing agent during excitation with l = 253.7 nm is the thiosulfate anion, which undergoes a phototransformation according to the following overall equation:…”

Existing data on photochemical and photocatalytic approaches to the formation of semiconducting nanoparticles and also binary semiconducting nanostructures and nanocomposites of semiconductors with metals and polymers are reviewed. The nature of the effect of irradiation on the synthesis and properties of the obtained nanostructures and the possibility of photocatalytic control of the structural and spectral parameters of nanostructural semiconducting systems are examined.The accumulation of data on the properties of semiconducting (SC) nanomaterials, which has occurred particularly rapidly in the last 7-10 years, has opened up ever more alluring prospects for their application as light-sensitive and light-emitting components in nanophotonics [1-3], nanophotocatalysis [2,[4][5][6][7], biosensorics [8][9][10][11], and other important fields. The possibility of practical utilization is an important factor that has stimulated the search for and study of the processes involved in the formation of nanomaterials. On this account an enormous number of publications have now accumulated on the improvement of existing and development of new methods for the synthesis of semiconducting nanoparticles and nanostructures (e.g., see the reviews [6, 12-15]). A special position among them is occupied by methods based on photochemical transformations conducted either for the purpose of synthesis and directing it along a desired path or for improving the characteristics of nanostructures produced by other methods.Photochemical methods of synthesis have proved more effective than the production of nanomaterials by traditional synthetic approaches, and in a number of cases only they make it possible to achieve the assigned aim. For this reason the synthesis of semiconducting nanostructures and their modification under the conditions of photoirradiation are constantly attracting the attention of investigators, and the number of publications devoted to these questions is constantly increasing. We note, however, that they nevertheless remain disjointed.In view of the foregoing an attempt is made in the present article to organize existing data, to identify the most important directions for research and development, and thus to assess the current state of development of photochemical approaches to the formation of semiconducting nanostructures. Analysis of data on the photochemical formation and post-synthesis photochemical treatment of semiconducting nanostructures and multicomponent nanocomposites, including the nanoparticles of metals and polymers in addition to semiconductors, showed that in spite of the variety and diversity of the proposed approaches all the papers can be ascribed to only three courses: synthesis, synthesis control, and changing the characteristics of the semiconducting nanostructures. For this reason in this review photochemical approaches to the synthesis of nanoparticles of metal chalcogenides, binary semiconducting nanostructures, and nanocomposites consisting of semiconducting and conducting polymers are examin...
