Overview

Review demonstrates dye remediation effectiveness using ecofriendly bionanomaterials in wastewater treatment, indicating sustainable alternatives.

Key Points

  • This review aims to explore ecofriendly bionanomaterials for treating dye-laden wastewater through synthesis and characterization.
  • Systematic review of various synthesis pathways including hydrothermal, sol–gel, microwave-assisted, and bio-based methods.
  • Evaluation of surface modification strategies and characterization techniques such as FTIR, SEM/TEM, XRD, BET, and Raman.
  • Analysis of adsorption capacities and photocatalytic efficiencies for dye removal.
  • Adsorption capacities range from 120 ± 5 mg/g for methylene blue on cellulose composites to 450 ± 12 mg/g for Congo red on biochar.
  • Photocatalytic degradation efficiencies reach up to 95 ± 3% under visible-light within 150 ± 20 min.
  • Bionanomaterials retain 85 ± 4% efficiency after five cycles of regeneration.
