“…In addition, most of the SnS or SnS 2 devices reported were fabricated using exfoliated flakes. ,, The practical application of this fabrication method is challenging, although it can reveal the potentials and properties of the materials. To address this limitation, chemical vapor deposition (CVD) was used for the synthesis of SnS and SnS 2 layers. − Although large-area synthesis is possible using this method, the layer thickness control, which is related to the performance of the 2D layered semiconductor, cannot be easily achieved. , Therefore, there is a need for a large-area thin-film growth method that can control the thickness, such as atomic layer deposition (ALD). − In previous studies, it has been reported that the piezoelectricity can be enhanced by forming 2D heterojunctions, such as WSe 2 /MoS 2 and In 2 Se 3 /MoS 2 . , Thus ALD provides a facile way to form a 2D heterostructure compared with other methods such as the exfoliated flake transfer method and CVD, allowing the exploration of similar effects in SnS 2 - or SnS-based heterostructures.…”

Recently, the inherent piezoelectric properties of the 2D transition-metal dichalcogenides (TMDs) tin monosulfide (SnS) and tin disulfide (SnS2) have attracted much attention. Thus the piezoelectricity of these materials has been theoretically and experimentally investigated for energy-harvesting devices. However, the piezoelectric output performance of the SnS2- or SnS-based 2D thin film piezoelectric nanogenerator (PENG) is still relatively low, and the fabrication process is not suitable for practical applications. Here we report the formation of the SnS2/SnS heterostructure thin film for the enhanced output performance of a PENG using atomic layer deposition (ALD). The piezoelectric response of the heterostructure thin film was increased by ∼40% compared with that of the SnS2 thin film, attributed to large band offset induced by the heterojunction formation. Consequently, the output voltage and current density of the heterostructure PENG were 60 mV and 11.4 nA/cm2 at 0.6% tensile strain, respectively. In addition, thickness-controllable large-area uniform thin-film deposition via ALD ensures that the reproducible output performance is achieved and that the output density can be lithographically adjusted depending on the applications. Therefore, the SnS2/SnS heterostructure PENG fabricated in this work can be employed to develop a flexible energy-harvesting device or an attachable self-powered sensor for monitoring pulse and human body movement.

Since petroleum resources on earth are not optimistic, developing clean energy has become a top priority. In this work, SnS@DAAQ-MWCNTs (SDC) with a honeycomb-like structure were successfully prepared by hydrothermal synthesis with SnS and carbon nanotube backbone wrapped in polymer layers as the anode for lithium-ion batteries. The electrode materials were characterized by measurements of SEM, TEM, XPS, XRD, Raman, BET, and TGA. The DAAQ-MWCNTs were found to be enhanced concerning dispersion, bringing better capacitive contribution. The SDC showed good cycling stability by CV and charge–discharge tests, demonstrating an initial discharge capacity of 762.8 mAh g–1 at 1000 mA g–1 and excellent rate performance with a recovery rate of 81.77%. This is ascribed to the special honeycomb-like structure, which enables the electrolyte to infiltrate the SDC electrode material better and swell the specific surface area for active sites.

The chemical procurer is an exciting phenomenon, which involves pervasion of various reactions on dissimilar media. The synthesis practicability lets the assortment of materials nanoscale, including oxides, minerals, alloys, and sulfides...etc. Research on inorganic materials will fetch ameliorations to innovative techniques, such as the nanostructure, morphology associated technique and description conjugation artistry. To obtain optimized synthesis performance with the inorganic nanostructures, however, numerous challenges as yet stay. More research and additional effort is needed to address the following important issues to enhance the practical preparations of nanostructures for inorganic compounds. This paper provides an inclusive review of recent and current researches that focus on the general technical method ways for synthesizing inorganic materials in different nanoscales. The chemical growth of particles in a nanoscale can be quite different from those of large quantities of substances or atoms and the individual molecules that make up them. Obviously, there are continued efforts by a large group of chemists to prepare inorganic nanomaterials, and behaviors both known and desirable for chemicals are worth and choose the appropriate methods. In addition, in this paper, it can open the way to illustrate the choice of the appropriate method for many researches.
