The rapid development of population, industry, and urbanization have generated significant issues including energy consumption and water contamination. Advanced materials are needed to clean up the surroundings and develop potential energy storage devices. Metal sulfides (MSs) nanomaterials are prospective candidates for multidimensional applications in medicine, biology, environmental sciences, and energy production/utilization due to their light absorption, optical characteristics, high specific capacitance, and catalytic/photocatalytic capability. Recent developments showed its use as electrode material for Li, Na, K, and Mg ion batteries, solar cells, and supercapacitors, electrocatalysts for the oxygen/hydrogen evolution reaction, sensors for gases/chemicals, and catalysts/photocatalysts for environmental remediation. Scalable techniques for producing high-quality, low-cost metal sulfides, heterostructures, and hybrids are needed to realize the potential of these interesting materials fully. This review summarizes current achievements in MSs notably, manganese sulfide (MnS), iron sulfide (FeS), cobalt sulfide (CoS), nickel sulfide (NiS), copper sulfide (CuS), zinc sulfide (ZnS), silver sulfide (AgS), cadmium sulfide (CdS), tungsten sufide (WS), tin sulfide (SnS), lead sulfide (PbS), and molybdenum disufide (MOS2) and their efficient physiochemical and biological production to get controlled morphologies, sizes, and compositions.

“…Among them, copper sulfide (CuS), with a relatively narrow band gap, is a nontoxicity, good photosensitivity, and excellent physical and chemical stability, eco-friendly and economic suitable materials [25][26][27], which make it as a potential candidate for visible light photocatalysis. However, like most single semiconductor photocatalyst, high rate of electron-hole recombination greatly hinders its practical applications as photocatalysts.…”

In this work, a novel organic-inorganic heterostructured photocatalyst: porous graphitic carbon nitride (g-C3N4) hybrid with copper sulfide (CuS) had been synthesized via a precipitation-deposition method at low temperature for the first time. UV-vis spectroscopy revealed the porous g-C3N4/CuS nanocomposites showed a strong and broad visible light absorption. Furthermore, the g-C3N4/CuS nanocomposites showed higher photocatalytic activity in the photodegradation of various organic dyes than that of pure g-C3N4 and CuS, and the selected sample of g-C3N4/CuS-2 exhibited the best photocatalytic activity under visible light. The good photocatalytic activity could be ascribed to the matching of the g-C3N4 and CuS band gap energies. Besides, photoluminescent spectra and photoelectrochemical measurements also proved that the CuS/g-C3N4 could greatly enhance the charge generation and suppress the charge recombination of photogenerated carriers. According to the experimental result, a possible photocatalytic mechanism has been proposed. Due to the high stability, the porous g-C3N4/CuS could be applied in the field of environmental remediation. Our work highlights that coupling semiconductors with well-matched band energies provides a facile way to improve the photocatalytic activity.

Photonic disinfection, particularly nearinfrared (NIR) light triggered antibacterial, has emerged as a highly promising solution for combating pathogenic microbes due to its spatiotemporal operability, safety, and low cost of apparatus. However, it remains challenging to construct NIRresponsive antibacterial agents with high light-converting efficacy and elucidate synergistic mechanisms. In this work, ultrathin two-dimensional (2D) BiOCl-Bi 2 S 3 -Cu 2 S ternary heterostructures that can efficiently kill drug-resistant bacteria were synthesized by doping 0D Bi 2 S 3 and Cu 2 S nanoparticles in the 2D BiOCl nanosheets via a facile one-pot hydrothermal method. Notably, the incorporation of Cu 2 S nanoparticles bestows strong NIR light-harvesting capability to the composite nanosheets due to their localized surface plasmon resonance (LSPR). Upon NIR light illumination, the BiOCl-Bi 2 S 3 -Cu 2 S nanosheets can achieve enhanced photonic hyperthermia and reaction oxygen species (ROS) generation, serving as single light-activated bi-functional photothermal/ photodynamic therapeutics. High-speed hot electrons and large local electronic fields caused by LSPR might play an important role in thermal vibrations and effective carrier separations, respectively. Benefiting from the unique ternary heterostructures, both the photothermal conversion and ROS generation efficacy of BiOCl-Bi 2 S 3 -Cu 2 S nanosheets are significantly improved compared to the binary BiOCl-Cu 2 S or BiOCl-Bi 2 S 3 nanosheets. Accordingly, the ternary composite nanosheets can effectively kill bacteria via the NIR-driven photonic disinfection mechanism. This work presents a new type of 2D composite nanosheets with ternary heterostructures for NIR photonic disinfection.
