A simple two-step hydrothermal method synthesized four different CdS/Fe₃O₄ photocatalysts with varying ratios of mass of CdS to Fe₃O₄. The composition and morphology of the prepared samples were investigated using X-ray diffraction (XRD), Raman spectrum, X-ray photoelectron spectroscopy (XPS), scanning electron microscopy (SEM), and transmission electron microscopy (TEM). Solid UV reflectance spectra testing found that CdS/Fe₃O₄ nanocomposites had good light absorption throughout the spectral range, promoting their photocatalytic properties. Under visible light irradiation, CdS/Fe₃O₄ (2:5) with a mass ratio of 2:5 exhibited excellent photocatalytic performance, with a degradation rate of 98.8% for rhodamine B. Furthermore, after five cycles of photocatalytic degradation reaction, the rhodamine B degradation rate remained at 96.2%, indicating that the photocatalysts have good photocatalytic stability.

This paper delves into the theoretical mechanisms of the electronic structure and optical properties of aluminum-based semiconductors (AlX, X=N, P, As, Sb) and indium-based semiconductors (InX, X=N, P, As, Sb) as potential materials for optical devices. Band structure calculations reveal that, except for InSb, all other compounds are direct bandgap semiconductors, with AlN exhibiting a bandgap of 3.245 eV. The valence band maximum of these eight compounds primarily stems from the p-orbitals of Al/In and X. In contrast, the conduction band minimum is influenced by all orbitals, with a predominant contribution from the p-orbitals. The static dielectric constant increased with the expansion of the unit cell volume. Compared to AlX and InX with larger X atoms, AlN and InN showed broader absorption spectra in the near-ultraviolet region and higher photoelectric conductance. Regarding mechanical properties, AlN and InN displayed greater shear and bulk modulus than the other compounds. Moreover, among these eight crystal types, a higher modulus was associated with a lower light loss function value, indicating that AlN and InN have superior transmission efficiency and a wider spectral range in optoelectronic material applications.
