“…For instance, treating the sodium thiosulfate (Na 2 SO 3 ) and concentrated hydrochloric acid suspension in a microwave oven at 200 °C for 20 min could realize the accomplishment of SNSs with lateral sizes ranging from 100 to 500 nm. [78] With the assistance of ultrasonic exfoliation method, sulfur powder suspended in the liquid phase system containing bovine serum albumin (BSA) even produces an ideal structure of SNSs. As shown in Figure 8d, sulfur powder and BSA aqueous solution were sonicated for 72 h, followed by centrifugation to collect the supernatant as SNSs.…”

“…The cathode demonstrated excellent cyclic performance with a charge capacity of 640 mAh g −1 after 500 cycles at a current density of 1 A g −1 . Besides, based on a simple melt‐diffusion process, [ 78 ] SNSs anchored on the silk fibers was successfully fabricated and utilized as a cathode material in Li‐S batteries, the specific capacity was increased due to the presence of soluble polysulfides intermediates. The resulted sulfur‐carbonized silk fibers exhibit a high initial capacity of 1231 mAh g −1 at 0.05 C and retain a high capacity of ≈997 mAh g −1 with a coulombic efficiency of nearly 99%.…”

Low‐dimensional sulfur nanomaterials featuring with 0D sulfur nanoparticles (SNPs), sulfur nanodots (SNDs) and sulfur quantum dots (SQDs), 1D sulfur nanorods (SNRs), and 2D sulfur nanosheets (SNSs) have emerged as an environmentally friendly, biocompatible class of metal‐free nanomaterials, sparking extensive interest in a wide range application. In this review, various synthetic methods, precise characterization, creative formation mechanism, delicate functionalization, and versatile applications of low dimensional sulfur nanomaterials over the last decades are systematically summarized. Initially, it is striven to summarize the progress of low dimensional sulfur nanomaterials from versatile precursors by using different synthetic approaches and various characterization. Then, a multi‐faceted proposed formation mechanism with emphasis on how these different precursors produce corresponding SNPs, SNDs, SQDs, SNRs, and SNSs is highlighted. Besides, it is essential to fine‐tune the surface functional groups of low dimensional sulfur nanomaterials to form new complex nanomaterials. Finally, these sulfur nanomaterials are being investigated in bio‐sensing, bio‐imaging, lithium–sulfur batteries, antibacterial activities, plant growth along with future perspective and challenges in emerging fields. The purpose of this review is to tailor low dimensional nanomaterials through accurately selecting precursors or synthetic approach and provide a foundation for the formation of versatile sulfur nanostructure.

“…A variety of possible photo-sensitive nano-semiconductor metal halide/oxides/sulphide, such as TiO2, ZnO, CuO, BiFeO3 and Carbon-based nanostructures have been produced and employed as photocatalysts for water purification, thanks to rapid advances in nanotechnology [11]. This innovative interdisciplinary branch of science and technology leads to the formation of different morphologies like nanoparticles [12-16][17], nanotubes [18,19], nanorods [20,21], nanocubes [22] and nanosheets [23] by using numerous advanced methods such as hydrothermal, solvothermal, sol-gel, microwave, co-precipitation methods [24] with different applications in many fields such as from basic chemistry [25][26][27][28], physics [29][30][31] to the advanced electronics [32][33][34][35][36], nanotechnology [37][38][39][40][41], biotechnology [42][43][44][45][46][47] by altering the properties like mechanical [17,48] physical [49][50][51] and magnetic [52,53] so they come up with an ideal of environmental friendly [54], with a motto of decreasing the pollutions [55,…”

Pollution by textile dyes on waterbodies is an issue for both human health and the environment. To remove/degrade dyes, many approaches (coagulation, membrane separation, and adsorption) have been investigated. However, the use of semiconductor-assisted materials in conjunction with sustainable solar energy has emerged as a possible solution to the problem. Although single component photocatalysts have been tested, composites of semiconductor materials are being employed owing to their low efficiency and stability due to the high recombination rate electron-hole pair and inefficient visible light absorption. By combining two or more semiconductor components, semiconductor heterojunction systems are created. Overall stability is increased by the synergistic impact of their features, such as adsorption and better charge carrier movement. This paper discusses current advances in advanced nanocomposite materials utilized as photocatalysts, as well as the utilization of heterojunctions, crystallinity, and doping to improve photocatalytic characteristics. The conclusion includes a summary, research gaps, and a forecast for the future. This study will aid in the development of efficient heterostructure photodegradation systems by providing a comprehensive appraisal of recent advances in demonstrating effective nanocomposites for photodegradation of Rhodamine B dye under ideal circumstances.
