Composite Material Formation Based on Biochar and Nickel (II)-Copper (II) Ferrites

Area of Science:

• Materials Science
• Catalysis
• Environmental Chemistry

Background:

• Development of advanced composite materials for catalytic applications.
• Utilization of biochar from agricultural waste (sunflower husks).
• Synthesis and characterization of mixed metal ferrites (nickel-copper ferrites).

Purpose of the Study:

• To synthesize and characterize a novel composite material from biochar and nickel-copper ferrites.
• To investigate the structural properties of the composite material.
• To evaluate the catalytic performance of the composite in methyl orange decomposition.

Main Methods:

• X-ray phase analysis
• Scanning electron microscopy (SEM)
• FTIR spectroscopy

Main Results:

• Successful formation of a composite material with oxide films on biochar, replicating its porous structure.
• Characterization revealed a decrease in unit cell parameters and cation-anion distances with increasing nickel content.
• The composite exhibited high catalytic activity, degrading methyl orange within 30 minutes via a Fenton-like system.

Conclusions:

• The synthesized biochar-ferrite composite shows excellent catalytic potential for organic pollutant degradation.
• The observed catalytic efficiency is linked to the composite's structure, including defects potentially induced by the Jahn-Teller effect.
• This material presents a sustainable approach for environmental remediation applications.
