splitting (2H 2 O → 2H 2 + O 2 ), consisting of hydrogen evolution and oxygen evolution reaction (HER/OER), can convert electricity to chemical energy in H 2 and O 2 for further energy applications. The practical application of overall water splitting, however, is still limited due to the lack of effective and stable catalysts to reduce reaction energy barrier and enhance Faraday efficient for both reactions. [6][7][8][9][10] Different materials have been studied for overall water splitting catalysis, like metal chalcogenides, metal carbides, oxides, etc. The transition metal carbides, especially graphene, have a better electroconductivity, ductility, and high surface area which display excellent performance in water splitting. [11][12][13] Oxides as another abundant species on the earth also show better water splitting performance, but their stability in hard media is not very good. [14][15][16] The layered double hydroxides (LDH) with unique structure, abundant interstratified electrons and channels for intermediate adsorption and desorption display wonderful water splitting performance. [17][18][19][20] Additionally, the metalorganic frameworks (MOFs) and their based nanocrystals as newly nanomaterials have got much attention in various fields, but their structure limited the active sites exposure for the complete coordinative metal sites. [21][22][23][24][25] Therefore, it is important to enable the cost-effective, large-scale production of these catalysts, and further improve the performance and efficiency of overall water splitting.Transition metal chalcogenides have many different compositions with various lattice structure, while those materials also have unique electronic structures. [26] Based on those superior properties, the transition metal chalcogenides show promising application in many energy applications, [27] such as electrochemical catalysis, photocatalysis, metal-air batteries, and other energy conversion reactions. Especially for their abundant defects sties, [26][27][28] tunable electronic structure, [29][30][31][32] and various morphology, [33][34][35][36][37] the transition metal chalcogenides exhibit boosting performance for water splitting. However, they still have some disadvantages, such as poor conductivity, activity, and stability, in water splitting limited their large-scale industrial application. [38][39][40][41][42] How to synthesize the active and stable transition metal chalcogenides is still a big challenge for wide application. In this Review, the several promising strategies are designed to prepare the active and stable transition metal chalcogenides (Scheme 1). → 2H 2 + O 2 ) is a very promising avenue to effectively and environmentally friendly produce highly pure hydrogen (H 2 ) and oxygen (O 2 ) at a large scale. Different materials have been developed to enhance the efficiency for water splitting. Among them, chalcogenides with unique atomic arrangement and high electronic transport show interesting catalytic properties in various electrochemical reactions, such as the ...

“…[4][5][6][7][8][9][10] Moreover, the bandgaps of these nanoparticles are size dependent, as particle size decreases, the bandgap increases, and therefore tunable. [11][12][13][14][15] As particles size becomes smaller, the ratio of the surface atoms to those in the interior increases, leading to a significant influence on the properties of the materials surface. 16 In recent time, IV-VI group semiconductor compounds have attracted lots of interest due to their optoelectronic properties.…”

Tin monosulphide (SnS) nanoparticles were synthesized by simple chemical method at ambient temperature. Stannous chloride (SnCl 2 · 2H 2 O) was use as a source for Sn +2 ions and sodium thiosulphate pentahydrate was used as a source for S −2 ions. The energy dispersive analysis of X-ray (EDAX) and X-ray photoelectron spectroscopy (XPS) techniques were used for stoichiometric characterization of the synthesized nanoparticles. While, structural characterization was done by X-ray diffraction (XRD). The particles size was determined from XRD using Scherrer's formula and Hall-Williamson plot. Optical absorption spectrum obtained by spectrophotometer showed sharp absorption edge at 520 nm, which acknowledged the occurrence of blue shift. The photoluminescence (PL) spectra of synthesized SnS nanoparticles for two excitations at 450 nm and 500 nm showed sharp emission peak at 825 nm. The transmission electron microscopy (TEM) image showed spherical shape of the synthesized SnS nanoparticles. The morphology of the synthesized nanoparticles was investigated employing scanning electron microscopy (SEM). The obtained results are discussed in details.

“…Iron disulfide (FeS 2 ) is an attractive anode material for lithium ion batteries because of its interesting characteristics such as high theoretic capacity (890 mAh g -1 ), low environmental impact and affordable cost [1][2][3][4][5][6][7][8][9][10][11][12][13][14][15][16]. However, the capacities of FeS 2 electrodes often reduce very quickly during charge-discharge cycling, especially at high current densities.…”

Iron disulfide (FeS 2 ) powders were successfully synthesized by hydrothermal method. Cetyltrimethylammonium bromide (CTAB) had a great influence on the morphology, particle size, and electrochemical performance of the FeS 2 powders. The as-synthesized FeS 2 particles with CTAB had diameters of 2-4 lm and showed a sphere-like structure with sawtooth, while the counterpart prepared without CTAB exhibited irregular morphology with diameters in the range of 0.1-0.4 lm. As anode materials for Li-ion batteries, their electrochemical performances were investigated by galvanostatic charge-discharge test and electrochemical impedance spectrum. The FeS 2 powder synthesized with CTAB can sustain 459 and 413 mAh g -1 at 89 and 445 mA g -1 after 35 cycles, respectively, much higher than those prepared without CTAB (411 and 316 mAh g -1 ). The enhanced rate capability and cycling stability were attributed to the less-hindered surface layer and better electrical contact from the sawtooth-like surface and micro-sized sphere morphology, which led to enhanced process kinetics.
