Two-dimensional (2D) nanosheets possess the very essential features of nanomaterials, including quantum-confinement effects and unconventional reactivity, and are of special interest for a variety of promising applications. Here we report a facile chemical transformation strategy to prepare porous ZnS nanosheets via the organic-inorganic hybrid ZnS(butylamine) nanosheet-like precursor prepared from zinc diethyldithiocarbamate. The hybrid ZnS(butylamine) precursor show unique nanosheet-like structure composed by ZnS nanocluster region and non-crystalline region. The ZnS nanoclusters with crystallized state show the same crystal orientation in the nanosheets. A simple calcination process in nitrogen can induce the transformation of ZnS(butylamine) hybrid precursor to porous ZnS nanosheets. Different calcination temperature will cause the formation of porous ZnS nanosheets with different microstructure. In addition, the photoelectrochemical properties of the ZnS-based products including ZnS(butylamine) and porous ZnS nanosheets were investigated. This organic-inorganic hybrid precursor strategy to porous sulfides would also be suitable for fabricating other metal chalcogenides.

Resource use is crucial for the sustainable growth of energy and green low-carbon applications since the improper handling of biomass waste would have a detrimental effect on the environment. This paper used nano-ZnO and ammonium persulfate ((NH)SO, APS) as a template agent and heteroatom dopant, respectively. Using a one-step carbonization process in an inert atmosphere, the biomass waste furfural residue (FR) was converted into porous carbon (PC), which was applied to the supercapacitor electrode.

It is proven through transmission electron microscope (TEM) analysis that solar sensitizer CuSnS (CTS) dots prepared via the hot-injection route are nonspherical, polyhedral nanocrystals with the size of ∼11 nm. CTS dots were deposited into a porous TiO layer to form CTS/TiO, an effective type II heterojunction in photoanodes. The electronic and energy band structures of TiO and CTS were studied by the plane-wave ultrasoft pseudopotential method based on density functional theory (DFT) and verified by ultraviolet-visible (UV-vis) spectroscopy.

Periodate (PI, IO)-based advanced oxidation processes (AOPs) provide an economical and sustainable approach to alleviate water pollution challenges. Developing efficient and stable activators for PI is the focus of current research. Herein, S/Fe-co-doped magnetic porous carbon material (S/Fe-ZIF-950) was prepared by introducing exogenous S atoms using Fe-doped zeolitic imidazolate framework-8 (Fe-ZIF-8) as a precursor, which showed the most superior performance (100 % within 10 min) in activating PI to remove p-chlorophenol (4-CP).

The uncontrolled deposition behavior and sluggish conversion kinetics of the discharging product (solid LiS) severely deteriorate the electrochemical performance of lithium-sulfur (Li-S) batteries, especially under high S loading and low-temperature conditions. Herein, a multifunctional S cathode host consisting of ZnS nanoparticles (NPs) confined in hollow porous carbon spheres (ZnS@HPCS) is synthesized via a unique capillary force-driven melting-diffusion strategy. The porous carbon shell of ZnS@HPCS provides a space-confined reservoir for soluble polysulfides and solid LiS, while the intracavity ZnS NPs trap polysulfides, induce LiS inside deposition, and accelerate conversion kinetics.
