Background:

Ferritin, an iron-storage protein, offers a biocompatible template for nanomaterial synthesis.
Developing novel nanostructures with tailored magnetic and catalytic properties is crucial for advanced applications.

Purpose of the Study:

To synthesize solid nanotubes composed of alpha-Fe2O3 nanoparticles using ferritin.
To characterize the structural, magnetic, and photocatalytic properties of the synthesized nanotubes.

Main Methods:

Fabrication of nanotube precursors via layer-by-layer deposition of poly-L-arginine (PLA) and ferritin.
Calcination of precursors to yield alpha-Fe2O3 nanotubes.
Characterization using SEM, TEM, XPS, IR, and EDX spectroscopy.

Main Results:

Uniform alpha-Fe2O3 nanotubes with a perfect one-dimensional hollow structure were successfully synthesized.
The nanotubes consist of fine alpha-Fe2O3 nanoparticles (5 nm diameter).
Demonstrated superparamagnetic behavior (blocking temperature of 37 K) and efficient photocatalytic degradation of 4-chlorophenol.

Conclusions:

Ferritin can be effectively utilized as a template for creating alpha-Fe2O3 nanotubes.
The synthesized nanotubes possess promising magnetic and photocatalytic functionalities for potential applications.
