Abstract
The improper and inadequate treatment of industrial, agricultural, and household wastewater exerts substantial pressure on the existing ecosystem and poses a serious threat to the health of both humans and animals. To address these issues, different types of materials have been employed to eradicate detrimental pollutants from wastewater and facilitate the reuse of water resources. Nevertheless, owing to the challenges associated with the degradation of these traditional materials post-use and their incompatibility with the environment, natural biopolymers have garnered considerable interest. Silk protein, as a biomacromolecule, exhibits advantageous characteristics including environmental friendliness, low carbon emissions, biodegradability, sustainability, and biocompatibility. Considering recent research findings, this comprehensive review outlines the structure and properties of silk proteins and offers a detailed overview of the manufacturing techniques employed in the production of silk-based materials (SBMs) spanning different forms. Furthermore, it conducts an in-depth analysis of the state-of-the-art SBMs for water treatment purposes, encompassing adsorption, catalysis, water disinfection, desalination, and biosensing. The review highlights the potential of SBMs in addressing the challenges of wastewater treatment and provides valuable insights into prospective avenues for further research.

Satisfactory degradation of tetracycline by a pH-universal CoFe-LDH/MoS 2 heterojunction catalyst in Fenton process. iScience 2024; 27:108996. [PMID: 38327796 PMCID: PMC10847731 DOI: 10.1016/j.isci.2024.108996] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/30/2023] [Revised: 12/06/2023] [Accepted: 01/19/2024] [Indexed: 02/09/2024] Open
Abstract
Fenton or Fenton-like reactions have been widely used in various fields, including solar energy conversion to generate hydroxyl radicals, environmental remediation, biology, and life science. However, the slow Fe3+/Fe2+ cycle and narrow applicable pH range still present significant challenges. Here, a heterostructured CoFe-layered double hydroxide/MoS2 nanocomposite (CoFe-LDH/MoS2) was prepared via simple electrostatic interactions. The heterostructure establishes a robust interfacial contact, leading to an abundance of exposed Mo6+ sites. Consequently, the developed CoFe-LDH/MoS2+H2O2 system exhibited superior performance in the degradation of tetracycline (>85%) within 60 min across a wide pH range from acidic to basic. Moreover, the CoFe-LDH/MoS2 heterojunction catalysts exhibited exceptional resistance to common anions and efficiently degraded various organic pollutants. The mechanism study verified that the CoFe-LDH/MoS2 had high efficiency in producing 1O2 and ‧OH to degrade various organic pollutants. The present study will serve as a foundation for creating efficient catalyst systems for related environmental remediation.

MATERIALS (BASEL, SWITZERLAND) 2023; 16:6960. [PMID: 37959557 PMCID: PMC10648990 DOI: 10.3390/ma16216960] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Subscribe] [Scholar Register] [Received: 10/11/2023] [Revised: 10/22/2023] [Accepted: 10/27/2023] [Indexed: 11/15/2023]
Abstract
Silk nanofibers (SNF) have great applications in high-performance functional nanocomposites due to their excellent mechanical properties, biocompatibility, and degradability. However, the preparation of SNF by traditional methods often requires the use of some environmentally harmful or toxic reagents, limiting its application in green chemistry. In this paper, we successfully prepared SNF using natural silk as raw material and solvent stripping technology by adjusting the solvent concentration and solution ratio (the diameter of about 120 nm). Using the above SNFs as raw materials, SNF membranes were prepared by vacuum filtration technology. In addition, we prepared an SNF/MXene nanocomposite material with excellent humidity sensitivity by simply coating MXene nanosheets with silk fibers. The conductivity of the material can approach 1400.6 S m-1 with excellent mechanical strength (51.34 MPa). The SNF/MXene nanocomposite material with high mechanical properties, high conductivity, and green degradability can be potentially applied in the field of electromagnetic interference (EMI) shielding, providing a feasible approach for the development of functional nanocomposite materials.
